You think that's bad? Just wait until you visit the same cave for the umpteenth time. Not an extremely similar cave from a cookie cutter mold (ala Oblivion), not even a mirrored version of the cave, the same exact cave. Trust me, you are going to be intimately familiar with said cave before the game is through.
Hey, let's be fair, most caves have differences between each other.
In one cave, the conspicuously placed rectangular doorway is free and clear In another, it's filled in with cement.
