I can see both sides, but I wouldn't really mind if they started doing "HHN Legacy" houses from 15-20 years ago and remake/reimagine them with modern budgets and creative philosophies. I feel like I would probably be a little more invested in the HHN Original brand if they brought back stuff like the Terra houses or Legendary Truth or even big name originals like Meaty Meetz or Bloodngutz. Then there's the issue of all-timers being literally lost to time in both memory and archival footage. I also really wouldn't mind it if they sometimes tried old ideas that just didn't turn out the first time. Like, once we get to that point in time, going back and trying to reimagine/remake Depths of Fear the way it was supposed to be would be kinda cool.
Of course, I wouldn't want an entirely old lineup. At most, a 1/4 or 2/3 split on Legacy/New originals. I'm pretty sure the creative teams are different now than they were then, so who knows how these houses could turn out looking like.
But again, throwing HHN30 Part 1's unused houses in HHN30 Part 2 is a lot different than even AWiL or what we are discussing here.
