We've seen some pretty excellent fan made games make the rounds recently; and more recently, end up being shut down as result of Digital Millennium Copyright Act. It's a shame too, with games like Pokemon Uranium and the Metroid 2 remake, and No Mario's Sky, Nintendo needs to take a minute.
Well fortunately, Sega's outlook on fan made games couldn't be more different. After seeing Game Grumps played Green Hill Paradise Act 2, Sega took note and sent out their approval on twitter.
