Maybe it's just my opinion, but I thought the Mega Drive/Genesis was a pretty good knock-off of the PC Engine/Turbografx-16. Yes, it has less colours and it took them a long time to finally add a CD-ROM drive, but some of the games ported from the PC Engine, such as Afterburner II, Outrun, Raiden, etc. weren't too bad for those people who couldn't afford a real PC Engine at the time.
