I've been toying around with the idea of making an async. card game for iOS, and I've been playing a bit of Triple Triad and Tetra Master lately. If I were to make a game based on those original game concepts, I'd want to make a proper tutorial, progression system, async game center support, etc. I've read some debates online about the two games, and it seems like a lot of people didn't like how Tetra Master's combat system was done (and lack of explanation on how it's rules worked). The general consensus seems to be that Triple Triad is the better game. I wonder what you guys think though?
