My wife recently joined a forum for mothers. ( she was jealous of BC ) and they have a games section. They have tournaments and such, and winners have little icons that go on the section to the left that displays location and what not.
I believe the games are links to sites where the games are hosted, but are somehow still part of their forum.
I can get more specifics if their would be interest.

i think they would slow the server and I know they would use a good bit more bandwith.

I think its cause the mothers get bored talking about their babies and that crap, they need something to look busy.

I don't know, it doesn't seen to affect them. Their site seems to run fine. I think it just links somewhere...I dunno. But I still think it would be cool to look into. But, i certainly understand teh concern of slowing down the server. I'll try to find out more about how it works.
