Tales of the Drunken Paladin

Tales of the Drunken Paladin is a fantasy-comedy RPG about a universally disliked hero who very suddenly loses absolutely everything - including his identity - and must go on a quest to find out who's responsible. It's also largely a game about interacting with thousands of inanimate objects. One full playthrough is between 40-60 hours. Once you've beaten the game, hard mode is unlocked.
