Haha... Seems like most people have their own framework.

I still have some doubts. For this compo, I will aim for absolute straightforward simpleness, because of severe time constraints (studies *bablabla*). So I will go for 2D and pick an engine I feel is simplest and easy to use. It will probably be either ZenGL or Phoenix (or maybe JEDI-SDL, but then I have to write myself a Sprite-engine too). I haven't made up my mind yet.
