I don't care about Dan Bunten's sexuality any more than I care about President Obama's or a billions long list of other people.
What I do know is that M.U.L.E. Is one of the greatest games I played as a child on my Commodore 64. Unlike many other games of the era, I still have fun playing it when I fire it up in an emulator. Saw in a comment in the site about www.mulereturns.com. Will have to buy that for my kids today.
