Mega Man 3 Intro and gameplay

Mega Man 3 Intro, and some bad gameplay by me :) lol
The intro music is awesome! How did they do it? :) The game is quite difficult, and take some time to learn and play through. The game is entertaining and you don't get bored, even after playing it several hours and days! :) Back in the 90's they made very good games with limited computer resources. Mega Man 3 is about 3 MB, and sold sold over one million copies worldwide, and Nintendo sold 61.9 million NES units worldwide!
