I got this because it was free but never did I expect how fun or addicting it would be, but thats exactly what poker is.
The gameplay is Texas Hold 'Em poker, but of course you knew that. There are multiple game modes in single and multiplayer. Each mode has buy-ins that range from being free to $50000. You can play a regular game of Hold 'Em on single player or multiplayer with your friends. You a given 3 bankrolls, 1 for single player, 1 for online and 1 for competitive playing. Competitive matches are tournaments where your put at a random table with 7 others and last player left wins. The other modes are basically just for fun but they still get competitive.
The graphics, well they sit right for poker, they aren't impressive but they sit fine with me. The only problem I can see is if you don't a HDTV you might have trouble reading some of the gamertag and possibly the cards if you have a smaller TV. I have no real problems personaily but the gamertags do look a little small.
Texas Hold 'Em is a lot of fun and can get very addicting. The different game modes and achievements give the game a lot of playtime and replay value. If you don't have this game the 800 MS points may be a little expensive for some but I would recommend this to anyone, whether they play poker or not.
