Garage Action Games Impossible?

How can you possibly make great action games while in the Garage?
Even setting max for Engine, A.I. and Graphics, my T/D is always closer to 1 then to 1.8. I suspect it’s because your main character has even T/D skills. I have tried using only engine features in those categories, best I can get is like 1.4 or 1.3.

Am I missing something or is this the expected behavior. Playing on Iphone 6
