Thanks for the replies, guys.
The engine is coded in C++. Most of the gameplay elements (UI, gameflow, NPC/enemy AI, etc.) will be found in scripts, which use a "C-like" language (with some light C++ elements).
Interesting. I ask because in the future I might also like to help move this project along by working on the programming side of things. Although I unfortunately don't know any object oriented languages, I am highly proficient in ANSI C and I have a moderate degree of experience putting my own (albeit relatively simple) game engines together. In the future, who knows? If you let me, I might be able to put some time and effort of my own into this.
Once the merger is finished things should definitely pick up pace.
I'm looking forward to that time, then. I know how difficult it can be to force yourself to plug hours of time into a project like this and see only a few (if any) immediately gratifying things at the end of your efforts, so I understand if this merger takes quite some time to complete. But hang in there, man. It will be awesome.
