Knizia must have at least a dozen games with different auction mechanics.

Also, if you’re looking for a pain-based game, see Shocking Roulette. Each player puts a finger on an electrode, the start button is pressed, and after some flashing lights one player gets an electric shock. The game can sense if one player tries to cheat by taking their finger off the electrode!

Yeah, BoardGameGeek lists over 4800 games with an auction or bidding mechanic. It's not that uncommon in hobby games.

There is also remote control tank games that I've played where when your tank gets shot, you get hurt.
