I just game across a site (gameduell.com) that promotes itself as the largest online games site in Europe, with 1.44 million players and ahead of others like AOL and Yahoo!
After a quick registration (pretty easy) and a play on their practice 9-ball pool game which is also available for real money (that's what they really want you to do) it seems like a pretty good site and to have a good number of players.
Game play was pretty good too, although I'm not a fan of pool games that have all of the angles showing where the pool ball is going to go. Where's the fun and skill in that

Anyone else have feedback on the GameDuell 9-Ball Pool game?
