Just like the board game, online you can always find someone to play against.
This visuals are true to the original, and even though it has a different view that tries to look more like an island, you will never use it. The only downside is that you can not play local, but this would ruin a little bit of the game as you could see you opponents cards. I understand why they left that out. The game has time limits to keep the play up to speed and though you can make them very generous in social matches, in ranked you need to keep on your toes.
I could go on and on about this, but the truth is if you enjoy the board game you will like this version. It is a perfect translation and one of the best games on XBLA!
