I'm pretty much in your boat; the only published setting I still give two hoots about is Planescape, and I still pretend that the whole Faction War thing never happened. I liked the DL Chronicles when I was a kid, but never actually played DL. I read a few 2e-era FR novels, but rarely play the setting. I still don't know what the Spellplague is. The Realms had another cataclysm, Mystra died again, yawn.So how about you? Do you get involved in the D&D metaplot? Or the metaplot of whatever game or setting it is you play? Do you participate in scheduled events by WotC or Paizo?
Oddly, when I read the Eberron sourcebook for the first time I felt like I was reading a post-event setting (I started with the 4e version) but it didn't feel as complicated as other post-event settings. I think this is because the war in Eberron was designed to create an exciting environment to adventure in rather than just shake up what had been a previously good adventuring environment.
D&D has a metaplot?
I'm right about here. My livingroom has a metaplot for each setting, but I don't want to be fed anyone else's metaplot.If I'm playing a homebrew setting, the DM usually has a metaplot, and that's the extent of my interest in metaplots.
