What sealclubber said. The crowd that appreciates EMs most is going to be those who grew up with them. If you had exposure in your youth to a 1975 EM and and a 2005 DMD side by side, you would instantly think the EM slow and basic. Those of us who grew up with them appreciate them more for the nostalgic factor.
That being said, I am surprised at the numbers of people who will still seek them out. There are lots of fun EMs even if they can't (nor shouldn't) compete with the SS and DMD games.
