One of the greatest games of all time for $5? How can you pass it up?
There's not much story to talk about. Peach has been kidnapped, and it's your job to rescue her. As moario, you have to run and jump through 32 levels, all set in different places. Some take place in the standrd world, others in waster or under ground. Boss fights take place in castles.
The emulation is spot on, with any glitches you remember returning. That means the infamous Minus World is full accessible.
The grahpics and sound are pretty much what you would expect from an NES game. The backgounds are very simple, usually consisting of a solid colour, or a solid colour with some clouds. The Music is good but limited.
There's not much to say about SMB other than if you have a Wii, get it. There's no better way to spend $5
