Sounds like fun but imo the last stage is complete bullshit. First of all it's a HUGE limitation to most of the mappers. For example a mapper that focuses on gameplay will have no problem while one that thrives through good looks will most likely stand no chance. Moreover, all the maps will look the same which is incredibly lame.

Making the tileset and selecting sprites is a very important aspect of creating maps, you should know that. Excuse me if I'm being rude but I find this ridiculous.
