So everyone is complaining about one area per planet thing. People are also complaining about the gameplay where they said you could go anywhere you could see basically. But what I think is that the areas on the planets are going to be big areas. In the beta there are lots of closed of areas which will be open in the full game. Now think, we can probably go beyond those areas that are closed off in the beta so it will probably be a big map. The game cost bungie a lot of money so it isn't going to be a small game you pick up, play for a while and then put down, it will be big. These are just my thoughts so we will just have to wait and see when the full game comes out.
