for this project, I do the first phase of the development of the project, because I finish the game engine project earlier, and Mo has to do his engine. And later phase is done by Mo, C# is just not so for independent development. may be I am just not famaliar with it. cause i am a c++ guy. I am not very comfortable with the c#. although it has some features that c++ does not have. But with c++, I have the control of memory, control of pointer stuff. I like that.
