It's not bad but I honestly have to say I'd prefer c++.
I don't think that there is something you can (and would) do in litec which doesn't work in c++ and on top of that c++ has some neat features.

The reason why I'm still sticking with acknex is because it's pretty lightweight (but kinda slow ),
offers a few handy functions (like handling strings, loading textures, sound, etc.) and because I
don't really have to care about compatibility (if it supports directx 9 acknex will most likely run on it).

edit: oh and that royalty-free thing is also really attractive.
