Online play has its flaws (one that should NEVER have been there).
In the first World Championship Poker game as well as World Poker Tour, it would allow you to hear other people on the microphone through the television in place of the USB headset. WCP2 doesn't allow you to do this.
Also, a feature in solo play was included in online play that should NEVER have been included. Just like playing against the AI in solo play, if you have a strong hand in online play, sometimes you will have a mini-bluff game that if you get passed it successfully, your player will either bluff or have a poker face. Because this is a 5-second game to cover up if you have a strong hand, this can be a MAJOR TELL in itself if others see that it takes a while for you to call or raise (if others are aware of this). This should NEVER have been included in the online play, and I really believe this hurts online play. That's where I believe World Poker Tour will have an edge over this game (when it comes to online play).
