The 5200 barely had any games that really used it in any meaningful way. There's a reason they went back to the original joystick design of the 2600 with the 7800. The N64 was one of the first real uses of it, YOU CANNOT DENY THAT!
As for this thread, it's trash. I'll buy what I want to buy within reason, and that's all there is to it. A 360 is not in reason and neither is a PS3. Both are way too expensive for something that supposed to be a leisurely pasttime after you purchase the system, the games, a live subscription in the case of 360, and an HDTV. I also didn't go buying all 3 systems last generation, mainly because outside of a couple games, there would be a favorite getting the majority of play while the others sit there collecting dust which is as far as I'm concerned it's a waste of money that could go to something far more important.
Release a quality GAME and I'll buy it, I'm not gonna care who made it. And when I say game, I'm talking quality design, not ART. All the art I'll ever want is on my wall and my movie collections, plus the work I do either for myself or for money. It's the very reason why whenever people bring up ICO, SoTC, Zelda WW, or even Okami I cringe. You want to talk about non-games, these are borderline. Yeah they look great, they're "epic", but the game design took a bit of a backseat in all of them.
