It not about the size, it about what in it. AC games gives you pretty much whole countries, but it is AC. VM:B has micro areas, and look how that great that game is (yeah it super buggy but still.) The map of fo4 needs to be even smaller, not bigger. Thus enriching what in it more. Not even general atomics, the old state house and mayor bunker? Or are you talking about quests and/or cities in general? .....Wut???? Would you be happy if the next Fallout game consisted of 2 city blocks? Had 1 dungeon, the Vault you walk out of and had a gigantic Achievement Get!!! when you left it signifying you won the game? Even smaller? The game is now barely a few miles wide, and is only an inch deep. You want to remove the only dimension the game is large. Do you go to forums for Turn based strategy games and complain they have too many turns?
