It doesn't have multiple story lines and is more in the style of Japanese RPGs, but I've rarely had more fun than with Anachronox. Stunning gem and a unique game. The plot is completely bonkers, starting off almost like a Blade Runner sci-fi noir story and somehow ending up with the party trying to save the universe. Combat plays a fairly small part in the game really, but it's fun, and the rest of the game is almost like an adventure game. It's a joy wandering around beautifully stylized areas (great use of the ageing Quake 2) and it's one of the few games which has made me laugh out loud on numerous occasions. Try it, it's very cheap by now, and it lasts a long while.
