Bethesda, in addition to a company, refers to several real-life locations, including the city the company was named after. For this reason, I think it would be clearer and more accurate to use bethesda_softworks instead of simply bethesda. I know it's not likely the city will get tagged but it seems better to use the proper name.

The fact that there's a wiki page for bethesda_softworks, the tag that was aliased away, and not the one it was aliased to, says a lot if you ask me.
