It'd be a pleasure to add the impressive No One's Space to the list! I wonder though, if it isn't more an OpenGL game than a SDL game (on the Steam page you mention OpenGL, OpenAL, no SDL though)? This is the same question I am stuck with for BeRo's impressive projects. I'm really interested in your thoughts about this (also BeRo's thoughts). E.g. if someone neutral asks you about your projects, would you answer "Yes, these are SDL games", or would you rather answer "Yes, these are OpenGL (or whatever) games"?

Hope you don't mind that I'm thinking about this rather seriously. If a game uses 95% other libraries, I wouldn't want the SDL showcase to fool visitors/readers/learners about what SDL is capable of and what not. - As a solution, I could think of a category "SDL assisted games", which would cover games which use SDL for crucial, yet minor parts (e.g. setting up an OpenGL context). Again, I'd be very interested in everybody's thoughts on this.

Anyway, I wish the best for your Greenlight period !
