It's good to see Mario can make fun of himself.

User Rating: 8.9 | Super Paper Mario WII
I find that some of my reviews are quite wordy and long. So, here is the abbreviated version.

Good:
- This game is funny. I laughed aloud more than a few times.
- The graphics are sharp and look good.
- This game is very fun. The different levels show a lot of variety.
- The length is quite impressive. It's about a 20 hour game.
- It is very casual, the difficulty level is minimal.
- Overall, the game is very charming because it doesn't take itself seriously.
- The 3D thing is not a gimmick- it's a great way to solve puzzles.

Bad:
- Too much text. I've had more than one person say something like "if I wanted to read so much, I'd get a book."
- Story is passable, but not terribly impressive.
- Pacing is inconsistent.
- No widescreen (seriously Nintendo... that is pitiful.)
- Very little voice work.

Verdict: Buy this game, unless you have a fair amount of time on your hands, in which case you can finish this game in a weekend.
