It's called not lasting. It's novelty, more than any redeeming quality, that people are generally loving in the first place- like in special-effects movies. Which is why games that have real redeeming qualities, like Deus Ex, Syndicate, Doom (sort of, it's more a historical landmark- if you haven't played Doom, you can't seriously consider yourself a gamer, which is, subconsciously or not, a distinction among nerds), and FreeSpace generally maintain a fair following long after the companies have closed and the mods stop flowing.
Which, let's face it, they have now. I've seen maybe two released, and one was a demo, since I came here. None in the past few months. Aside from SCP upgrades, which are pretty cool but far from standalone, we're basically playing the exact same game over again.
