I wouldn't dismiss the retro gamers. There are lots of folks who love to drag out older stuff they've never seen before and rock those games. My cousin who was born in '94 has an NES, genesis and a c64 and he loves those games. Stuff he definitely didn't grow up around.
I went to one of those thrift/retro hip stores in Raleigh a few weeks ago. I saw a bunch of teenagers pining over an amiga 500 playing lemmings.
