Theme of new maze could be good as I guess scary/creepy dolls can be effective. Not sure how you make an entire maze out of it (e.g. in the attic at AT there is a toy scene which is cool) but I guess we will see.
It does also put me off going to fright nights nowadays the fact that you get one chance (unless you're buying multiple entries) at having a good run through on a maze, so I tend to go on what I predict will be the quietest day (maybe the first Sunday), and STILL the couple of times I've gone I've ended up in a huge group with a load of teenagers and there's hardly any actors in most of the rooms hah. Go figure...
I will say, mazes like asylum with strobes, loud noise and general chaos meant that, even though you were going through in quite large groups in a conga line, you still always got good scares and in a way it didn't matter so much about where you were in the group, it was still intense. I think thorpe may now be missing a maze which has an intensity like asylum (and to some extent creek freak) had, but who knows maybe stitches will bring that. Haven't done survival games so can't comment on that.
I hope they do consider things like this when designing mazes, I.e. how will it perform in sub optimal conditions, rather than when one influencer goes round with the full cohort of actors.
