I would probably try to re-make a high quality version of Master of Orion 2, Endless Space is okay but feels too empty and has no soul, in other words it lacks the fluff of MoO2. Also, it would be cool to have Dungeon Keeper reborn, I have heard of Maia, but that is in Space. So yeah, I would want to design games of the past to modern capabilities of the PC. Oh and if I had unlimited money I would get rid of all consoles, they suck and hold back innovation.
