Well yeah, I think I was a bit unprecise with my question. The real question was like "Is jPCT-AE powerful enough for semi-amateur games"?. To clarify, I don't intend to compete with high-class game developers like Gameloft. All I want to do, is code some nice 3D games, which people will say "hey, this might look cool, lets try it out". On a side note, they will be released for free of course.
The problem I see is, that jPCT-AE looks a bit restrictive in some ways. For example the way Object3Ds are handled. For me, I'm used to load an 3d model into memory, and then created as many "instances" of it as I want. In jPCT-AE it seems like you have to clone that same object over and over again. That said, the javadoc makes many many comments about this and that is memory wasteful.
Don't get me wrong. I'm only using jPCT-AE for serval days now. It's just that I don't know what to think of the engine yet. Its a kind of question like "Am I forced to use this engine cause it is the only one out there, or do I want to use it cause it is actually a good engine?".
So long,
Kernle
