Hey, there's room for every setting, and these days, with so much ice cream and cookies, and brownies, and fried octopus and sauted snails, a guy craves good old fashioned pie now and again =)
Dragonlance is my choice because there is so much rich detail in the setting, and loads of history and culture. And with the new DLCS, theres finally room to play with all that, without getting tripped up by novels. Greyhawk is dead, the realms are stagnating, and all these other settings are too different (scarred lands), too dark (midnight), or too dull (KoK) for me.
Thats not to say that other people might not dig it. After all, even FATAL has a following somewhere =)
