@Geoffers747

• What engine/language are you developing this in?

“We wrote our own engine in C++ and Open GL.”.

“The core engine is written in C++11 and Open GL. We write all the gameplay and AI in LUA. Finally, we use JS and HTML for the UI.”

There’s your answer, I suggest checking the QA thread made by @Geoffers747 next time as it has alot of info.
