2012-2014 it was a Maze and Terror Tram, 2013 started the scarezone trend. Finally 2015 killed the dominance of TWD and allowed The Purge to start taking overSeems a bit ballsy to include Leatherface or Jigsaw to the tram when they have their own maze but I wouldn't really mind it, I just know some if not a lot will though. Didn't TWD do this for some years when it was a scare zone and a maze?
Unless Chucky and Jigsaw were planned in the first place, they haven't been added. John said a while ago that the tram has not been changed. So unless the original rumor of Freddy, Michael, Jason, and Leatherface didn't include details of Chucky and Jigsaw or they were added after John said there's been no changes then it'll probably be the Big Four
