To end the Street Fighter 25th anniversary and to start Mega Man's own 25th one, Capcom released this free PC game for all. This is a classic NES looking and sounding Mega Man game, but with the Street Fighter cast replacing the robot masters.
I haven't played it yet, download still going and I have to leave for work, but I can't wait to get it! 
Oh and they say it's not as hard as Mega Man 9 or 10, so that more people are able to enjoy and play it. That's a good thing in my book. 
Edit: Added the link for downloading the soundtrack of the game!
