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 than 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.
