Like, out of the games I play? Jeez. No clue. At some point, unless it's just a really exceptional game that I'm eagerly looking for more of as soon as I finish an update, I usually don't think about it until the next update.
That said I do like My Girlfriend's Friends, and that game is closing on something like a year and a half with no real updates (but plenty of random sketches and pinups from the dev).
