Today the Football World Cup starts down in South Africa. Now I would write something about the football and how great of a sporting event any sport’s world cup is, but I don’t really know that much about football apart from their are eleven players and what I’ve managed to pick up from loosing 40 or 50 games of FIFA 10.

So whilst I’d feel remiss if I didn’t at least make an attempt at connecting today’s discussion to the World Cup, I can’t really write about the actual event. So after hours of racking my brains I (and by I, I do mean teflon via Twitter) came up with the idea of teamwork. I mean there’s an awful lot of that in football, and it isn’t really something I’ve touched upon yet.

Whilst there are the obvious occasions of teamwork, primarily in sporting games, what is becoming more common these days if teamwork and partnering in other genres. Although co-op has been around since the days of arcade dominance, it seems to have had a significant growth on consoles in recent years. This new level of co-ordination and teamwork that’s been brought into gaming has helped to revitalise some genres for me, adding new set pieces and making campaigns feel a more social experience.

Of course the one major issue here is if the AI understands how to work as a team.

Some games have the AI’s team work nailed almost perfectly. For me Gears of War is definitely in this group, whether or not you have a human partner playing along with you the game continues to flow correctly and you feel supported by the AI if you’re playing by yourself. On the other hand you’ve got titles like Killzone 2, where it seems your AI partners frequently decide to shoot the wall instead of valid targets.

This is only made worse by the lack of co-op, meaning you’re stuck with inefficient AI partners who don’t really seem to understand the basic objectives, let alone how to work as a team.* From my experience with Modern Warfare 2 I’d say it seems to suffer heavily from the same issues. I have distinct memories of my team mates running around doing not very much.

Of course how could I miss out the teamwork involved in increasingly large and complex online games. From watching my old flatmates play raids on WoW it’s clear that the level of co-ordination involved in modern MMOs really is above and beyond any other genre. Sure there are some clans in shooters that are incredibly well coordinated, but they seem to be the exception rather than the rule.

It’s perfectly possible to be successful in a shooter with almost no co-ordination, a raid in an MMO seems impossible if you’re not well coordinated. MAG seems to have tried to resolve this, but I’m not sure how successful it’s been.

The issue today is I don’t really have a question to ask you about teamwork. I guess I can boil it down to simply ‘do you enjoy it?’. Do you like working as a team in games, or do you prefer to play the loan wolf? Do you like games that encourage team work, or do you prefer to be left to your own devices.

Finally here’s a little teaser for next week’s Lunchtime Discussions. They may have something to do with a little expo going on in Los Angeles. You know, in case you couldn’t have guessed that highly classified information by yourselves. Enjoy the World Cup!

Note: My Killzone 2 comments are based on video I’ve seen and complaints I’ve heard. I may have been misinformed, if so I apologise. Lee did call Rico “as useful as a third armpit” though.

  1. The stuff about killzone 2 is both right and wrong. In some instances, Rico is useless and pathetic; however he is extremely useful in the fight against Radec as he helps to reveal to you where he is. It depends on the scene.

    Me, i like playing as a team and on my own, whichever i feel like :)

  2. I personally think co-op is great for gaming, it’s much more social and can be a great laugh but it all depends who you’re playing with, the amount of times I’ve tried to initiate a posse in RDR only to be shot in the face is annoying.

    The upcoming RDR co-op looks great though. I’d say best co-op game at the moment is Borderlands, great fun

  3. AI teammates are a difficult one, because if they’re good you could just hang back, and they’d kill everyone leaving you to just hide your way through the levels

    So from a gameplay perspective I can’t really see how they can be changed.

    Online is different, I have most experience of Warhawk so I’m going to relate to that.
    If you play in a full 32 player server as I always dothen as long as the opposing sides aren’t total n00bs it isn’t possible to Capture The Flag and get it all the way across a map which takes several minutes to drive across unless you do have teamwork.

    If the defending team is well ‘dug in’ then you will only get the flag out of their base with a simultaneous air and ground attack, it also helps if someone has called in a binocular strike on defending missile silos a fraction of a second before your air support gets there, who need to fire an electric bolt from their aircraft to clear enemy mines, drop a cluster bomb to clear the small army of stragglers who are all armed with rocket launchers and then send at least 2 jeeps in, it also helps if each jeep has at least one extra person in it because the stragglers with rocket launchers are lethal. A defending tank will always take at least one out and then you have to get the hell out of dodge, again this is easier with air support otherwise opposing aircraft will just bomb your jeep on the way back.

    On the PS3 this sort of organisation is difficult because only a small fraction of people have headset and even fewer actively use them when not playing with friends.

    I love it though, and if I happen to join a poor team, I have just as much fun playing lone wolf, fucking up the enemies coordinated attacks

  4. Spec ops in modern warfare 2 really is very good. Spent many a happy hour with my brother online trying to clear all the veteran missions. Happy days. Mag is fantastic when you’re in a game with a squad leader who has a headset, or when i’m squad leader. Co-op definitely is on the up, and i’m glad about it. However sometimes it’s just not appropriate for me to be barking order down my headset, for example after midnight when mrs and baby are in bed. During that time i have to go solo.

  5. The problem with friendly AI is that they’re completely useless in order to let you do all the work and have fun. But often they’re so useless that they detract from the fun.

    I’m going to use MW2 as my prime example here. In the sections where you’re clearing houses in the suburbs, your AI is completely useless. There’s no sense of actually clearing a house, and they’re far too eager to just get to the next way point. So much so that there’s usually 3 or 4 Russians camping out upstairs who’ll simply pop a cap in your face if you so much as creak a floor board.

    But their blind idiocy is compounded by their massive health bars. The only way that their poor path finding and survival skills could be balanced out to give them a semblance of being “good” was to ramp up their health to 10x the enemy’s and respawn buddies as and when they die.

    It’s actually quite shocking to think that the friendly AI has barely improved since, not just CoD1 but right back to MOH:AA. That’s almost 10 years with barely any change to the AI. Poor effort.

    But it’s difficult to sort this out since most people that play FPSs have absolutely no military training, and so don’t know how to work as part of the team. Not to mention it’s not as fun if the AI does everything for you.

    It’s quite a conundrum. I’m just disappointed that it’s not got any better lately.

    • on the other hand enemy AI has gone up massively.

  6. Not so much teamwork but partnership for my comment. Uncharted 2. I had major reservations when a mate told me that around 70% of the game will be with one or two people (eg. Elena, Chloe, etc). However, after playing the game, I realised that it was absolutely fantastic to have them along with Nate. The banter, the emotion, the storytelling. All sublime.

    Coming back to AI party members. Yeh, not so cool. Is there even a balance to strike? They could clear a room for me or be utterly useless. I wonder, do we have games where if AI party members get killed that the difficulty lightens up a bit (and vice versa)? Would that work?

  7. Some people here have commented on the fact that AI hasn’t really progressed much in the past few years. It’s true I guess – there were days when people used to remark how in new game x the AI is really good (usually enemy rather than ally AI though), because it was a new(ish) concept.
    In some games AI has improved from the days of Ghost Recon where your allies would run into your gunfire (not just line of fire, but while you’re actually firing), causing you to fail your mission. And in some games not so much (played Lost Planet 2 lately?).
    It seems to largely depend on how much the devs have decided you should be doing, and for most part it boils down to the player should hold the key and the AI are mere distractions. It would be hard to create an AI which was perfect, as mentioned because it would make playing the game somewhat redundant if they were too good, and you’d feel like you were babysitting if they were inadequate.
    Therefore most devs play it on the safe side, giving you a sense of superiority at the same time.

    As for teamwork in games, I prefer it unless the rest of the team aren’t even trying. In that case I would ideally prfer team work, but must turn to going solo to preserve my sanity.

  8. This won’t quite be the essay some other people have written on here, but why not have 2 difficulty settings, to change the enemy AI behaivour & one for ally AI?

  9. I definitely prefer to play alone. And I especially love when I’m defeating a team of other players all alone.
