kbd here to tell you the good and the bad of Paper Mario in as few words as possible. ;)
The good:
+ 10 - 20 hours approx. single player mode augmented by optional challenges
+ charming and genuinely funny
+ good artistic design (graphics and sound)
+ good characterisation and story
+ robust turn-based combat system
The bad:
- bosses tend to be easy
- lots of dialogue
- lots of backtracking
