Wasn't there an article on HN recently about fishing old games for gaming concepts? I wonder if someone took up that idea and thought that the next best course of action was to conceal their source before blatantly ripping off every classic game mechanic from the last 30 years? After all "Good Artists Borrow, Great Artists Steal" I really can't imagine any other reason to target BBS games specifically. Also, the deleter happens to be a programmer as well.
