If by “game world” you allow TRRPG’s then it’d be Golarion (Pathfinder 2e) and last nights game was “Case File #4” where a creepy leather bound book (the ‘Dark Archive’) keeps appearing and transporting us to various other places to fight undead.
#4 was an abandoned mansion overrun with undead that we needed to clean out. Fuck almighty almost every room was a combat session!
So to be teleported there I’d just run away. Even if I could find a suitable weapon I’d not survive more than one encounter. Not worth throwing away my actual life for some stupid book!
