Update: Version 3.0 of Super Mario Bros. Crossover is now available. Click here to start playing!
Imagine being able to play the original Super Mario Bros. as Mega Man, Samus Aran, Simon Belmont, Link, Bill Rizer or even Mario. Dream no further because thanks to Exploding Rabbit now you can.
Super Mario Bros. Crossover is as close to a picture perfect version of the original Super Mario Bros. as you can get on the web. All the additional characters (Samus Aran from Metroid, Simon Belmont from Castlevania, Link from The Legend of Zelda, Bill Rizer from Contra and Mega Man from Mega Man) look, sound and behave as they did in their original games. Even the music for the stage changes depending on who you choose.
Which character to use and when definitely depends on the level. I highly recommend using Simon Belmont on 1-2. His throwing axe will break through most of the blocks added a brand new experience to the game.
As a classic gaming purist I cannot give this game a higher recommendation.
