Well, I have finally played it. By next week I will have modded my Wii too and will be playing it at my own house.
I liked everything about the game except for a bit, so I'll list that. By the way, Ike is my favorite in the game and much different than Marth (though they have similar fighting styles).
The target tests progress in levels, and I'm not even sure there are original target tests for each creature. Apparently you unlock them as you beat Classic, and we could only do the easy one in our desperate attempt to unlock Lucario. So as far as we could gather, the target tests are not unique to each character.
Some items are hard to see/distinguish. What we thought were the motion sensor bombs are realistic looking this time, and we had a hard time seeing them. It was especially funny when I had one of those black hole bombs and threw it at random, then ran into it.
