Well it depends if it's on the computer or on xbox 360/ps3... I don't know much about computer online games but I hear a lot about World of warcraft and Diablo but it's not my thing... If not there's imvu, second life or those online games that appear in pop-ups I guess... Personally, I only play Call of Duty online on ps3...

The Amazing Muffin Game.
It's like a role play and you can do anything. You just have to get the muffin and all the other players have to get the muffin.
You just say, hey let's start the muffin game.
Then you start it.
Example:
I have the muffin. I put it in my pocket and run to the Alps where I'm guarded by wolves and dynamite in a cave and you can't get me.
All the other players have to find a way to get that muffin.
