I downloaded this game tonight and it is awsome. My wife NEVER plays video games and she played this with me for about 3 hours tonight. I wanted to quit and SHE wanted to keep going. It has split screen and live MP which is nice.
Before you write it off as another quicky block smashing game it's not. You have to make poker hands to clear the cards and you can set up combos and stuff like other games. The poker hand gimmick really makes it fun. I can't remember how many times I forgot to look for a flush and probably passed them up. I miss them in real poker too.
Anyway, if you are looking for a cheap fun game for your 360 grab this. It's really fun. Get Assault Heros too if you don't have it.
