Not really. The game has grown so apart from the game maker's original intentions. Just compare Diamondus Warzone to Distopia or Semiconductor. The fact is, the community's idea of what is good is different then the game makers. The same goes for tilesets. Tilesets are expected to have working water, snow, pinball events, the works. Plus all destruct scenery, et cetera. Eyecandy galore, transitions between ground and background. I could go on.

Official tilesets are nice, but claiming that there is no need to use player made tilesets just is over the top.
