WARNING:
Spoilers, Bad Language!- The Adventure mode is quite long but the story is good at best. Also, there were situations where this mode should've supported 4-players co-op considering the amount of characters there are to select. We completed Adventure mode in 10 hours!
- Unlocking characters through Adventure mode was great.
- The final boss of Adventure mode is WAY~ overpowered. Expect to die several times and maybe even cry.
- They should've added the ability to select different characters once you die (such as: during a boss fight). It was frustrating when you're trying to beat a boss.
- Great list of fighters but could've used more.
- New "Finishing Moves" look cool.
- Updated Classic mode offers new unlocks to the game, which is great (such as: Break the Targets - Level 2).
- Mini-games (such as: Events) and other modes (Home Run Contest) now support 2-player co-op! However, unlocking more levels in the Events mode could've remained the same as Super Smash Bros. Melee (where completing a level unlocks another one).
- New collections makes the game more replayable to the hardcore crowd (not me).
- Features, such as: build your own stage and the ability to save replays are a great addition!
- Unfortunately, we didn't touch the online multiplayer mode since we were very tired. Hope to update this in the future though when I manage to want to play the Wii again...
