3D does more for gaming then motion control. What I mean by that is it helps games, particularly Nintendo games, when you can actually tell how far away something is rather then imagining it. I was quite surprised how different it was playing Pilot Wings on a 3Ds vs. wii sports resort on a wii. It was like the first jump to the third dimension games made during the era of the PS1/N64/Saturn. I am very excited to play Zelda/StarFox/Mario on this thing. Just for the record, I hated the wii, and never saw a bright future for it, but hopefully things will go well for this hand-held.
Also, a new console is only as good as it's launch list? So tell me, what decent games came out with the Xbox 360/PS2 when they launched?
