Pros:
+ Best story mode out of any Smash game
+ Great music
+ Excellent side content
+ Cool first-party newcomers
+ Last game to have Target Mode
+ First Smash game to include a Stage Builder

Cons:
- Nearly unplayable as a competitive game, due to
• Tripping
• Very little hitstun so true combos are difficult to impossible to execute with most characters
• Extremely unbalanced characters, with Meta Knight and Ice Climbers being some of the only viable ones in higher competive play
- Art style feels dated and especially doesn't look good on a 480p Wii
