I don't know,I haven't played it either. I just know the character from brawl. It sounds like the game will be good though...
Well it was pretty awesome on the NES. You go around slaying beasts, collecting treasures and hearts and such. If it does come out on the Wii, I doubt it'd have any of the upwards-scaling, continously moving stages and side room exploring of the original. It'll probably be more of a LoZ type adventure game.
It was for the NES and it is on the virtual console already. It is rumored that a Kid Icarus sequel wil lbe announced this year for Wii and that Pitt was made so godly in SSBB as a way to market him to the newer audience
