It's at: Game Table Online.
What's so cool about it? It's not the usual chess, checkers, backgammon.
They have games from Out of the Box (publishers of Apples to Apples) and Cheapass (publishers of Kill Dr Lucky), amongst others.
All the games are interesting, with nice interfaces.
I just finished a nice game of "Kill Dr. Lucky". It will be nice to finally have someone to play with. It's free to register there and you get the first two weeks free. After that, if you decide to play it's only $4.99 a month (which seems pretty reasonable compared to some of those online RPGs and stuff). Hopefully, more people will discover this place and be online (it's kind of a ghost town right now).
I'll be checking back throughout the day to see if there are people online for any of the games...
