Maybe something like Scripting and Engineering?
Reverse Engineering sounds ok..ish, but also sounds a little too specific and might cause threads that should go there to be put in places like General.
Game Engine Investigations, while correct in describing the board, sounds very uninviting and more suited for QGears.. I honestly like Tech Related more.
Inner Workings isn't descriptive enough I don't think and would rely 100% on the board description for people to know what to post in it.
Game Mechanics isn't bad, but also reminds me of GameFAQs and doesn't really sound like a board for strictly serious inquisitive posting
