I still, to this day, can not understand how a videogame, especially areas, can be too big for people. There was not a single game yet, that had too large areas, people's attention span is just shrinking and shrinking. You want story rich quests, don't like fetch quests and "my boot has a hole, bring it to the Smith that is 10 meters away" Quests, but don't like running through a nice landscape? I honestly don't get it. The problem most people have, is not the game, that is too large, but that no one is willing to enjoy a videogame, for what it is, anymore. You want to have action, wanna get shocked, wanna get all the stuff in the game as soon and fast as possible, defeat the last boss and new content and more content and even more content, just to rush through that stuff, too.
People scream and shout, that Call of Duty is for kids and people who got the attention span of a fly, but no one wants to walk through or stare at a beautiful landscape. There have to be enemies, dungeons, houses and loot, even though it doesn't make any sense.
Stop this "don't make the game too big" madness. People wanted lots and lots of content from BioWare in dragon age inquisition. Once you got it, you complain how there's "too much to do"... either I got hit by a meteor or everyone's out of their mind. I don't understand "gamers" these days.
