Indeed. I don't think a few more years makes much difference in the appeal (or lack thereof) of E.R. Eddison, Lord Dunsany, Abe Merritt, or Edgar Rice Burroughs. It is not really a matter either of when one was born or how old one is now.The interesting thing is that it's a generation gap of CULTURE, not age.
I am not acquainted with Old Empires. I think Dark Sun (and Planescape) came out when I had washed my hands of TSR and moved on to other things -- but would probably have suffered (perhaps unfairly) from my weariness at the time of all things remotely "Orks ... in ... Spaaaace!" anyway.So I naturally loved Dark Sun, Maztica, the Old Empires, Empire of the Petal Throne (yes I know how old it really is).
