Most of the panfandom games did (now that I think about it I actually don't know much about the single fandom games, sorry) after the layout for comment pages changed in a way that kills long threads and badly affected accessibility, and one of the head people at LJ basically said in an interview (unfortunately I don't have the links any more) that he didn't really care about what the current userbase wanted as long as he attracted new users with the changes to the site.
