I don't know anything about Steam, but people seem to be split vs whether it's good or evil. I always prefer having the discs so I always buy them if they are available. I bought the Anniversary Edition because it was on sale and come with some extra goodies. I think one bad thing about Steam, or good, depending on your point of view, is that you can't choose whether to install updates or not. With a hard copy version, you can download and install updates yourself.This would apply to "Official" N3V updates of course. 3rd party updates are done manually in either case.
