This below has to be my favourite part of Silent Hill 2, the only way to go forward in the game is by jumping into a big black hole, of course, you don't REALLY have a choice after jumping down the first one, but the game decides to ask you, then rewards you by seemingly trapping you in a well...happy days!
Also, pretty much any part of Project Zero/Fatal Frame - The game that forces you to take pictures of fricking freaky looking ghosts to kill them xD
