I'm looking for a fun co-op XBLA game with a friendly community

Hi, I'm not very good at video games (especially shooters), and it seems like every time I play online people just spend all the time yelling at me about how much I suck. Are there any games with nicer communities? I remember on the PC Worms:Armageddon stood out and I actually made a bunch of friends from around the world playing that game.

Thanks!

Try X-Men Arcade. You can jump in and out at will and most people seem nice enough.

There are a couple of Worms XBLA games, or maybe something like Castle Crashers or Lara Croft?

It's tough to find friendly and helpful people on XBL. It's not impossible, but it's tough.

Does it have to be XBLA? When I played a lot of Borderlands co-op, pretty much everyone online was friendly and helpful. There's not much of a competitive element to the game and the difficulty and stress levels during co-op are generally low.
