I think perhaps the question is "Is Sega's output from the 80s, 90s and early 200s being forgotten" and to a large extent this is due to licensing issues. We all know the issues with Sonic 3, but a lot of iconic Sega output is tied up in licensing hell. Want to re-release Daytona? Need to check whether we're still allowed to call it "Daytona". Want to re-release OutRun, we'll need to check with Ferrari. Want to re-release Sega Rally? Toyota and Lancia might need to be involved. Wouldn't it be nice to finally get some home ports of Star Wars Arcade Trilogy or Jurassic Park Lost World, oops sorry, need to renew the license. Want to play the remake of Castle of Illusion? you'll have to pirate it because our license ran out. Want to play Crazy Taxi? Not with the original soundtrack, sorry. A large chunk of Sega's back catalogue is just not immediately accessible, and is really only available through piracy, which is a crying shame.
