Maybe it's just me, but wouldn't it be awesome if a lot of our favorite games had a create-a-map mode or something similar? Kind of like the Left 4 Dead ones, but for all platforms. Creativity can actually keep a person playing for quite some time. For instance, in Minecraft or Halo 3 or Reach, you might spend hours creating a single map or structure. I'd just like to get other peoples' views on this idea. I'm not saying to have creativity in every game, but for games that it can actually work with like Left 4 Dead, Call of Duty (maybe,) or even Assassin's Creed (singleplayer for practice on targets, or multiplayer to have fun with friends.)
