Both Puzzles & Dragons and the Mario version of the game I have played a few hours and have to say that the original much better than the Mario variant.
While it has been well implemented for Mario conditions, but I like the real monster much better, In addition you can walk around in Puzzles & Dragons in the city which suits me much more. Also think that the Mario game is a bit heavier, and it is also feasible.
The combat system is initially not precisely what you are used to, but it is great fun and fight for some one already knows some tricks to good combos perform, because you, the spheres can be as moving as you want and therefore more colors together in a can bring 3 or higher chain, which then leads to the attack.
