Paper Mario is fantastic. Great gameplay, fun characters, and plenty of charm. In many ways, it's a lot like Shadow Hearts: Covenant, with a timing system that adds spice to the turn based battles, and a whole bunch of fun and bizarre side stuff to discover (although nothing as weird as SH:C's dog fighting system, with the pre-match smacktalk between the dogs
).
Total 10/10 for me (or 5/5, or whatever). Loved every second of it.
