Some of my fondest gaming memories come from offline and online cooperative play. From old school titles such as Battletods, Final Fight... through to X-men Legends, Twisted Metal... to the modern day classics like Halo, Ghost Recon and Gears of War. And I'm positive Halo 3's four player cooperative campaign will further cement this decision, less than a month away now. :D

All of the above, I'm up for competitve and cooperative, just depends :)

Co-operative, lots of fun to be had! Duke Nukem 64 is one good example

I'm only competitive if its a local LAN party

I voted none! :P

I'm primarily into gaming for the single player experience.

Playing multiplayer with actual people in the same room as you is fun (especially with alcohol), but I've only had bad experiences playing online.

The few times I've played online I've been the noob surrounded by a bunch of pros who are into the game really seriously, and they'd get shitty at me if I wasn't very good at it straight away.
I'm just in it for a bit of fun, I'm not wearing my clan t-shirt and doing the official salute.

All of the above for me.

Competitive is great fun, especially on small, fast-paced maps. Co-op is equally as awesome, what, with games like Halo and Gears of War lying around.

If I had to choose though, an MMO world is probably my favourite, even though I've had relatively few experiences with the genre as a whole. The opportunities for RPing and losing oneself in the world itself are endless. :P

Can't beat multiplayer. :D

All of the above for me, that option is good for, depends on the mood.

Same, I always seem to prefer the single player side of things. Multi is great and everything but there is so much more depth to the single player experience imho.

I'd have to say I've almost completely stopped playing single player altogether. Only rarely do I play a single player game, and its usually as practice for some kind of multiplayer game. :P

If I feel like "pwning" people obviously competitive, but co-op is great for when you wanna, well, co-operate. ;)

I haven't really played much online lately, but I'd choose both competitive and cooperative, but there wasn't a choice for just those two, so I chose all of the above. I don't really know about shared, would that be like MMORPG style or like Flatout UC stunts style where you can't see the other people but you compete for scores?

For me I would put the 'shared' aspect under say, a test day in my formula one league, where we drive around the track in free practice, but don't actually race each other but rather hone our own car setup. Of course, sometimes theres a bit of smashing but thats not the idea :P

I love to play single player as well mind you, but in the long run when I've completed the single player I'm only going to really get alot of joy out of playing it again maybe 1 or 2 more times, so depending on how good the multi-player is (if it even has it) then that makes a huge factor.

Co-op absolutely.
It made Future Cop LAPD an absolutely awesome game.
As well as countless others, Timesplitters 2, Final Fantasy CC etc.

All of above for me. Either way I pefer to play with people I know rather then strangers, trash talk is all the more sweet if you can bring it up all week afterwads.

Co-Op for life, Sven-coop, Ultimate Alliance, X-men, Halo, etc. The best mutliplayer is working together.
