It real anoys me that even when your in an building it still snows or rain while your inside. Even Minecraft stops it from raning/snowing if you are stasning unerneath a block. The thing that anoyed me most was when you had completed Oblivion and in the dragon temple, (where martins dragon statue was) even if it was raining, when you went inside and looked out of the broken roof, it was always sunny. This needs to be fixed to make the game more realistic (not that it is completly realistic like). That is my main thing tha anoys me.
