Your five dollars is better spent on some better VC games, as this Mario title isn't worth it.
Now to the actual review. For $5 this may seem like a true bargain. However, there are better NES games that still aren't outdated, like this one. It's not graphically amazing for the system and wasn't anything spectacular then. Okay, it was one of the first Virtual Console games, and it's Mario, but it doesn't work. Of course, two player support is there - work together or annoy your partner. But even he/she will get bored with the repetive stages. They're all the same, the enemies are too easy to beat, and the high score system is worthless. It should be an arcade game that you can pop in a few quarters and get playing for quite a while, then leave. Whether the amount of quarters then added up to $5 in a home console form is up to you. But it's not recommended and the game was on as a free addition to the Super Mario Advance games that you can still pick up for about $13 nowadays, with graphical improvements and the such. Plus, a small mini-version was included in Super Mario Brothers 3, now downloadable for the Virtual Console or in GBA form. The game legendary, and all these re-releases shows that, so there's no need to get the game already.
