this engine currently cannot do much except from load moddels and allow the user to fly around, this is not the goal for the engine and i am currently working on actuall gameplay elements!
the tuesday engine is an open source game engine that will be lightwieght and customizeable. also completley free to use (for now at least)
on AMD and INTEL processors this will work if you compile the libraries properly, otherwise this is not built for arm or anything.
