I think, if Sony owns the rights to it, a standalone game with the original rules would be great. The main things I loved were the direction based attacks, the variety of cards, and the elemental/flippable game tiles that could affect a lot of different classes.

They made a PSP version of the game I used to play WAY more that the PS3 version, but I think the people who bought the full game had a sour taste in the mouth when they found out you could print the right code and “own” whatever characters that were in the booster packs.

When the hell is someone going to make a mobile version of that game? It was so much fun!
