This was the first game I got for my GBA, and man was I disappointed in Nintendo, why porting 1 game, that has been on Mario all-stars? It's still fun to play, and great for people that never played the original on the NES.
They did add a few things, like bigger pieces of fruit and bigger enemies.
The character and bosses no have voices, and you can collect special coins, and eggs in every level.
If you already beated Super Mario Bros. 2 on the NES or on Mario All-stars don't get this game, if you never played Super Mario Bros 2, get this game, it's still as great as all those years ago!
