No offense intended at all, but I'll yet-again reiterate the misconception everyone seems to have about pixel-art games. People make SNES/NES/Genesis-inspired indie games because making pixel art is typically much easier than making a 3D game. You will see '64 and PS1-inspired games when development tools get a fuck-ton easier to use (although we're already at serious diminishing returns on that front, referring to Unity), because, let's face it, '64 and PS1 games look like total fucking trash, while SNES-era games are both gorgeous and easier to make, while also being much more iconic to many more people. And nope, "most current indie devs" didn't grow up in the SNES-era. It's 2014. There are a shitload of indie devs who grew up on PS1 and '64.
Pretty much this. Early pixel and 3D have important places in gaming history for what they ultimately ushered in, but I wouldn't think either are in much need of nostalgia driven revivals. IP's from the era sure, maybe even the gameplay, but not the art itself.
