Dark Souls, without a doubt.
There's nothing like getting your arse handed to you and knowing it was because you weren't good enough, or took stupid risks, or thought you could kill a dragon with a sword, or thought you could take on a pack of wolves, or thought it was a good idea to jump off a ledge, or being greedy and getting shanked while looting a corpse, or the myriad of other ways the game will try and make you its *****.
