Ralph

Ralph is an enjoyable game. It is consistently well-written and well-implemented. Your character is thoroughly believable. The fact that you play an average, run of the mill, house dog makes the game that much more enjoyable.

My only qualm with Ralph is its shortness. There aren't any glaring bugs or typos, and the writing never loses voice or style. If you like playing a game with a non-human player character, go for it.
