heck no, I just need to add the code in there that exports the engine to dlls. shouldn't take too long, maybe a day. the functionality of the engine all gets exported to a dll, and then in the game project instead of you seeing the implementation, all you get to see is that all of the classes of the engine itself is imported from the dll. you have to know how to use dlls to know what im talking about. i haven't worked with them in a long time though
