To me half the fun is in creating new lore in a beloved, unfinished Universe, as in not piggybacking on the backs of others all the time.
That's not RPing in the universe you came to RP in.
Everything you've just stated is an opinion: "That's not really RPing in the universe that we came to RP in."
Oh really? I believe I'm still RPing in the same Universe, though perhaps on a less developed planet or in a less developed region. Which allows us the ultimate opportunity as fans, the opportunity to create.
