The game that spawned an entire genre! Take on the character of the famous Italian plumber to run and jump through the increasingly difficult levels, all the way to the big final boss, Bowser! Save the princess from the huge and evil Bowser!
If you loved that (who wouldn't?) and would like some more classic Nintendo NES gaming action with the famous plumbing duo we recommend trying other games from this series like Super Mario Bros. 7 V0.1 (SMW1 Hack), Super Mario Bros. 2 and the third to the throne Super Mario Bros. 3! Get that princess!
