#8 because it is as outdated as I am okay, a more serious one: I've ever planned to develop only for Windows (sadly not sponsored by Bill Gates), and to make an in-game editor (i.e. I don't need a shiny editor like in Unity).

#9 imo the easiest 3D game engine to start with. lite-c supports experimental way of programming used by hobbyists like me, code debugging is not a big pain (despite a lot of missing features in SED), that enables me to develop a quite complex RTS game system. object oriented programming would require a more professionally structured programming (I am trying to achieve it).

#10 because it is possible to win a pro license. it gave my project a significant performance boost, that now meets my requirements (and finally prevented me from switching to Esenthel engine last autumn, which was a good decision, as I cannot customize there the movement and collision system without engine source access, what is easy with lite-c).

#11 collision is not bounded to PhysX only

#12 low system requirements both for development and playing.

#13 I know it well enough, and have made my tools I need.
