Oh my God, it's gotta be Two Worlds.
One of the poorest open-world RPGs ever conceived, and yet also strangely awesome and entertaining. I have to say that the main character makes it in that game. His 'mad dislocated limb flailing' method of combat never fails to make me laugh, not to mention his constant shouts of 'DIE CUR!', 'DIE DOG!', 'DIE FIEND!', and my all time favourite: "IT'S RAINING. DRIP, DRIP, DROP."
Also, they accidentally made the Wyverns in the game have the pig snorting sound effect instead of some generic growl. Nothing short of genius.
