Bethesda games in general are buggy pieces of crap but they get away with those problems because the games are AMAZING. Seriously go load up Skyrim, find a mountain, climb it, then look out at the view. It's breathtaking how beautiful they make their games. When they're not trying to make everything crap brown that is. And even then the sheer scope of all that destruction is just....amazing.
Ironbite-simply amazing how much you can add to it too...*launches nukes at Super Mutants from the Washington Monument*
