for C#, I only know unity and neoaxis (ogre based), which are actively developed.

would be possible but i don't like the idea of a small white window opening every time i open a level (except one is already open)

i don't understand neoaxis (the engine is pretty good but i have no idea how the core works)

I tried Axiom, but the samples didn't compile...

Also a lot of other free 3d engines don't fit my coding style and code requirements (this is just personal but i really hate bad coding style)

But i've done some other engines before and the worked really good (except my OpenGL renderer, but that's another story)

yes, I had the same problem with neoaxis, it offers a large code package like udk, but without a good tutorial going through on it, while udk has some programming tutorials... one of them says: 75% of coding time is reading existing codes, maybe it is valid for neoaxis too...

maybe you should not stay with c#...

how have been made 2GEN ? they have only used some GUI on top of 3DGS ? or do they have used another language and some other engine API ?

why shouldn't i stay with the language i master perfectly (or nearly)?

btw, small update:

because it's only one language

Because you should use the right tool for the right task. Ie if you want to write a Jabber server, learn Erlang because that's what Erlang is for (well, actually it's for telephone systems, but series of tubes etc). Yeah, no idea what this topic is about or why you asked that question, but I wanted to say something

LOL

this thread went totally offtopic so you can say anything. but I agree, I meant the same.

Which white window? Just reset the nexus with level_load(NULL), clean your internal stuff and call the open-level-function
