Besides the lack of online play and single player challenge, Mario Super Sluggers is a REALLY fun multiplayer game!

User Rating: 8.5 | Mario Super Sluggers WII
This game needs a lot more love in my opinion. Even though not too many people like the Mario Spin-off games (Mario Party, Mario Golf, Mario Tennis ,etc.), Mario Super Sluggers is better than you think it is.

Story:
Mario and friends sail to Peach's new island simply called Baseball island to (obviously) play some Baseball until Bowser and Bowser Jr. (AKA Baby Bowser) come crashing into the island and taking it over with their minions running amok. Its up to Mario to round up an all-star Baseball team and defeat Bowser to save the island.

Controls:
Lot of motion-sensitive controls may seem tiring (only if you overdo it) but it makes you feel like you're really playing Baseball. Now with the rest of the controls, it depends on what type and there are 3 types(technically 2): Nunchuk, Wii Remote upwards, Wii Remote sideways. With the Nunchuk, it'll be satisfying for those who want complete control over their team, Wii remote upwards will satisfy those who want it plain and simple with few controls and sideways will satisfy lazy people who don't wanna use the motion-sensitive controls XD

Gameplay:
Its just your average Baseball game but with Mario characters and features from Mario Kart and Mario Party alongside previous features from Mario Superstar Baseball.

Graphics:
Graphics in this game are MUCH better than Superstar Baseball and also adds a little more brighter, relaxing touch to the game. As for the cutscenes, it lacks a TAD BIT of the gameplay graphics but its nothing too dramatic and looks kind of similar to the Super Smash Bros. Brawl cutscene graphics

Sound:
No complaints here. The voice-acting, music, sound effects all blend in really well with the game.

Fun Factor:
In single-player mode, it won't be as much fun as it should be in multiplayer due to its lack of challenge but may keep you busy unlocking all the unlockables in the game. As for multiplayer, this is where the game truly shines! Multiplayer mode is a blast with friends who are new to the game or veterans of Superstar Baseball.

Bad Side of the Game:
Mario Super Sluggers lacks online play, which there is no excuse to why it shouldn't have online play in the first place....I personally think it would be fun if it had online play. The challenge in the single-player Challenge mode doesn't live up to its name considering it can be beat with in an hour or two. The game itself also doesn't seem to appeal to other hardcore or casual gamers and makes it seem unnoticeable and underrated in my opinion.

Overall:
Mario Super Sluggers will satisfy most veterans and newcomers to the game. Aside from the lack of online play, challenge in single-player mode, and appeal to hardcore and casual gamers, Mario Super Sluggers is most definitely a must play!
