This is the pinnacle of the homage game. While I would say that Thousand-Year Door is a more polished, and overall better than this game, Bug Fables is no slouch.
Ultimately I dislike this kind of game for what seems to be the whole point of it. However I truly believe that Grim Fandango was worth playing despite that. I think it's the most promising point and click game out there.
I understand why people don't like Extra, since most know what they're getting into, but I urge you to at least try doing the optional routes in it. Its the best part before Alternative.
