Are you really asking us, the people that hang around on the gamesas forums, how we could sue Bethesda? And over a buggy game?
There are no grounds for a lawsuit there.
To be blunt, yes I am asking you the people who lurk on the Bethesda Forums. Its not that its just a buggy game, the fact is the bugs that do exist are game breaking and stop users from getting what they paid for, a functional game. I bet Bethesda could fix these problems with a patch and thus far they haven't tried.
Key words: Broken. Product.
