Yeah, rather than do a single “everything” house like M&M, it’s structured more like 2010 with anniversary “stuff” dispersed across a few houses. Smartly, though, this design covers a much wider variety than any previous anniversary did. The only issue is that, for all intents, nothing prior to 2000 is really represented based on what we know so far.
It’s possible SCarey has a scene from before 2000, but I don’t really see it based on the scene names. The earliest year I think could be in that house is 2003. Maybe they’ll use a lot of nods in the zone design. It would be nice if the anniversary zone had characters like Michael Krueger, Eye-gore, or Darkness.
