Whatever goes in Mystery Lodge will be fantastic. I don't think they've ever had a bad maze there. As for the other maze, I'm hoping they pick another spot -- I'm not a fan of the Xcelerator location. And truly, I hope something else bites the dust -- 2 new mazes don't feel like enough at all. I think KSF should be doing a bare minimum of 3 new mazes a year. Origins would be my pick -- I know it has its fans, but nobody is going to be genuinely mad if it goes without an announcement, at least not enough to boycott lol
Personally, I would love to see a grounded aliens maze, could be modern or in the past, doesn't matter to me as long as it's not mostly set in space ala Dead Entities, and it's not a comedy.
I feel like it's been a while since we've had something in the medieval era. Would love to see something cult-ish also.
