Why does everyone talk about replacing lite-c? Nobody said lite-c should be replaced, but extended. A port to a new language instead of only C/C++. Although I don't see the point in having a hook to Java other than "convenience". It's more advisable to learn C++ straight away as C++ allows more than Java does on win32 systems, which is what 3dgs is designed for. Javascript may be more flexible than lite-c, but it's generally equally easy when you take in account all other factors, plus you will only be limited more (don't know javascript that well but I think the extra possibilities you get on javascript-side will not make up for the limitations you create with it on engine-side.
