Make "Assassins Creed Infinity" where I put a different historical figure on the "Animus" to bring it to life within its unique time and setting! Sell 'em for $15-20 a pop, and let me mix and match character and setting. Done.
I just love the engine and mechanics at this point, so whatever gets me in there I'm at least half interested in. But they really flushed the last shits I could give about the story down the drain with AC3. So they can do whatever on that front. Just make the missions not dumb this time.
