Halo Reach had it right. You could build YOUR OWN level however you wanted. Why would 343 NOT expand upon that!?! My friends and I spent hours building sweet maps and I saw so many that other gamers came up with. It was a huge success! However, instead of taking this awesome feature to the next level 343 neutered Forge World and forced us into pre made maps that are far too small and cluttered to do anything imaginative. I would say this is a massive blunder on their part. I hope they rectify this mistake soon. Anyone have any thoughts?
