SMA and SMA2 take first and second place on the top ten gameboy advance games, but I must recommend SMA. SMA2 was good, but if you already have SMW, then the game is hardly changed, so it won't last. But SMA was changed a bit, to bring up the ... stuff. Giant POW blocks, more enemies, new score, different parts in areas, and Mario Bros. fit in with SMA, not SMA2 because of the SMB2 background. So if you don't have SMW get SMA2, but if you do, get SMA. Or, even better is Wario Land 4!
