Mega Man 3

The third part, which takes a big step forward in terms of variety and innovation. Everything that was good about the previous game has been improved and added to (though not without bugs and bad optimisations). Megaman has learnt how to do a roll-up and has acquired an assistant - a robot dog called Rush, who can transform into a feather, a flying machine and a bathyscaphe. There are many more adventures to be had before you enter Wiley's Fortress, and the plot itself is enough to keep you interested. In terms of music, the game is as good as the second part, and even better.
