My brother has reached this point in BP, and I'm like "Well I dodged a bullet with that one...". I'm glad people are enjoying it though!
I have to admit it would probably have got me if they'd just gone for like, "ancient lost civilization" aesthetics (i.e. exploring ruins and tombs) rather than "big mysterious house" aesthetics.
(I assume an ancient lost civilization is involved somehow given some of the screenshots I've seen but the aesthetic primary very much appears to be "mysterious post-Victorian mansion".)
