I have found that the main WPT site has one of the most realistic game play for online poker. It's by far the closest you'll to playing in real life. A side from reading your opponents tells all other aspects of the game are true to the real deal.
Ring games, also known as cash games, offer an exciting alternative to tournament poker play. You choose how long you stay in the game, and chips correspond with their actual value, either in real or play money.
World Poker Tour’s online offers such popular ring games as No-Limit Texas Holdem poker, Omaha Hi/Lo, and Seven Card Stud. Whichever game you prefer, you can play it in World Poker Tour’s online poker room.
Be sure to swing by the WPT site and down load there online gaming system and give it a try and you'll see for yourself what I'm talking about.
