Abject Suffering

The wild swings that developers took on the PS2 are infinitely fascinating, and one that you don't hear too much about is Dog's Life. It's a bad game, but there's not much else like it. It's open-ish world, you play as a dog, and you can shit and piss at the press of a button. One person does all of the voices, and the ending needs to be seen to be believed.
