Naw. Monaco is for F1.
VEGAS BABY!
You're right, Vegas is for babies (=
Now, on the actual topic of the skilled play and challenges to be overcome.
Can there be a real challenge if the person controlling the opposition is both aware of what I'm doing
and unconstrained? I can see a challenge in besting someone in chess, or winning a Flames of War tournament, or something like Dark Souls or Rasputin song in Beat Saber.
I don't know if I could call a game or chess, where my opponent can just pull new pieces outta their ass and place them whatever they please a real challenge. If I win, the only reason for that is... I was
allowed to win. Same can be said of Resident Evil 4 with its dynamic difficulty.
Even with that "impartial judge" stuff, the GM is the one who built the damn dungeon — the only reason there's no another trap that can't be detected by looking up, down and all around without shouting a very specific incantation first is simple. It's not there because the GM didn't put it there. They could, and I'd be rolling 3d6s again. There's nothing to stop them from doing that other than their mercy.
