Simply labeling it the best poker game on PS2 doesn't make it perfect however; far from it. WCP suffers from some glaring flaws particularly the almost useless single player portion of the game. A good question to ask yourself while playing solo is "What's the point?". There is no career mode you pick from a quick game or a tournament. There are eighteen different poker variants you can play, which should provide variety for the avid poker fan, but pretty much everyone plays Texas Hold'em online. The AI in solo mode is probably the biggest flaw because the computer almost never bluffs. AI betting big? Fold because it's got you beat. It's almost like playing Poker against your mother. If only Vegas was as transparent.
In fact, the only way to justify the $20 budget price is with online play. Here predictability goes flying out the window seeing as how you're playing against real people. The Sony Eye Toy camera can be used to view each other's faces while playing, but not recommended, seeing as how it causes serious lag issues, and thanks to the low quality of the picture you won't be able to tell if your opponent is bluffing or choking on a peanut. Keyboard and voice chat are also included and work much better than an actual camera.
Don't buy this game if you don't have a Network adapter and are never planning on purchasing one. Take it online, and chances are if you have an interest in poker, you'll get your money's worth and enjoy this title. If you're buying it for single player action then you should like winning, because you won't EVER lose.
