Personally, I'd rather play Super Mario world and Legend of Zelda than most of the games on Live Arcade. One of the reasons is that they're known quantities, whereas many of the Live ports have been very dubious in quality (anyone who made the mistake of getting Contra knows what I'm talking about here). Everything from Nintendo has been incredibly well emulated, with the added bonus of being able to have a "save state" that means you can pause the game, turn off the console and come back to play later. Man, I wish my NES and SNES had that years ago.
So while I'd come down on the side of the Wii in this debate, in the end it's totally personal preference on the games - just like it always is with this console debates.
The next version of the jetpack is planned to have take off, longer flight time and aerobatic capabilities."
