I know it's really childish, but I've always been a huge fan of Neopets. I love all the little mini games. I like AddictingGames.com as well (especially Cake Wars), but the thing I love about Neopets is that you get points for all your scores and you can buy furniture and dumb things like that. It's just fun and makes me feel like my game play is actually going towards something.

There is also Pogo.com where you can play games and attempt to earn money or prizes, although I've never won money from there, but the games are still fun and great time-wasters!

Couple problems with WoW
1.) He said free. Unless you play on private servers, that's not gonna happen.
2.) "what r some good online games?" He wants to play a good game. Not a completely boring game that wastes all of your time

let's see,
online games make one go no-life?
and..
hmm,
Lineage 2?

Perfect World,great game + F2P

Call of Duty 4.

Lineage 2 , World of Warcraft

Do you mean like WoW or COD4 or other games like MMOCC's like Habbo US ~ Home which I have heard is quite good. I don't play it though

well this is more like a chat room but habbo.com is good!
