My variation on that is "a great game is great anywhere so long as it is built appropriately for its platform". Some are fine with playing GTA3 on their smartphones over consoles, yes, but for some it's not ideal, and there's going to be games that work even worse for it like Mega Man. At the same time I would NOT want to play something like Kirby: Canvas Curse or Superbrothers: Sword & Sworcery on a traditional controller, and even among games built for controllers something like Street Figher is far from ideal on the standard 360 controller.I said it once and I'll say it again:
What matters are the games not the platform.
If the game is good then the game is good no matter where you play it.
I don't play games on my iPod Touch MUCH, and given the battery drain I probably would be even less inclined to do so on a smartphone, but they have a niche they fill well and so do more traditional handhelds, and while I'd prefer to keep traditional handhelds of the two I STILL think it'd be more ideal if they can co-exist.
