I think the perfect DMC5 would be if they break the mold of having 20 levels and make it have 30 levels. you would play 10 as Nero, 10 as Dante, and 10 as Vergil. All 3 characters would have at least like 4 or 5 devil arms and each of them would be as in Depth as the Red Queen in DMC4. and after you beat the game you can play through any level you want with any character you want. And also bloody palace would be more like the one in DMC3 where its not timed and you can choose to go up 1, 10, or 100 levels after you beat a level. to me that would be the best game ever made.
