Regardless of your feelings on the comic strip or the guys who make it, 4CR think that Penny Arcade Adventures does certain things that are desperately needed in this industry. They refused to compromise on content or distribution (they basically told GameStop to screw themselves), and they made the game that they wanted to play.
If you're looking for a fun little RPG and have an appreciation for Cthulhu, steampunk, or Adult Swim, 4CR can't recommend this episode enough. They don't think that $20 is too much to ask for six to eight hours of playtime when those hours are better than similarly-lengthed $60 games.
