All Star Mode is very fun in this game. The characters from the same game series are grouped together, and you fight them on one of their stages. For example, I fought Mario, Peach, Luigi, and Bowser on the Mushroomy Kingdom stage the first time I played All Star Mode, and I fought them again on the Luigi's Mansion stage the second time I played. Characters like Yoshi and Wario are in Mario games but still have their own series are fought separately.
This mode can be very tricky, even on easy mode. The use of items in the game can be very helpful, but they can also be a major setback. When I played All Star Mode for the first time, I played on easy mode. I was hoping to beat this mode with no continues so I could clear a challenge. I was doing very well the entire game. When I got to the last character, a bomb appeared and fell on me, sending me flying. So much for beating All Star Mode with no continues!
Two player All Star Mode should be an exciting way to play the game. I have not gotten a chance to do two player All Star Mode, but it looks very fun.
