I can do nothing and frankly, I don't see why I would. Authors are not supposed to speak up in defense of articles about their work; if the practice isn't expressly forbidden, it's at least incredibly gauche in the eyes of the Almighty Wiki Editors and my arguments, of which I have little to none, would hold as much water as a gnat's navel by sheer virtue of simply being the guy who came up with the thing. I'm not urging anybody to do anything on my behalf, either, because I don't dig the whole "GO FORTH MY PRIVATE ARMY AND LAY WASTE TO THOSE WHO HAVE OFFENDED YOUR LIEGE" thing and honestly, if the article sufficiently offends the Wikipedians' tender, obsessive sensibilities, let 'em take it out of their playground. The game is still listed in the archives and repositories which count for Interactive Fiction, such as the IF Archive and the IF Wiki, and there it will happily reside.
The only thing that upsets me is that it's a pointed reminder that fame eventually fades and popular culture moves on. This is no surprise and it's certainly no new lesson for me, but it still, well, stings, y'know? Notoriety, however, can flourish in the right circles. And I have to say PUTPBAD is doing all right, circle-flourishing-wise, for a one-joke game written eighteen years ago, and that's fine by me.
I wonder what to do next.
