As long as the emulation is perfect, I'm happy to pay a few bucks for old titles.
I'm no Nintendo fan boy, I've had all different consoles in my life and was really unimpressed with Nintendo when they released the Gamecube, seemed like the target audience is now for kids. I have the same sort of feelings about the Wii, it seems more like a childish console, but consoles like the Xbox360.. pretty much represent everything I hate about console gaming. Rehashed PC FPS games and overly complex/hard to use controls. I really hope the PS3 dosen't go the same direction, I loved the PS1 and PS2.
