A: I think the thread title is a bit misleading, Kiki Wolfkill (Gotta love that freaking name!) seems to be more implying that she wants Halo to be the best it can be.
B: Star Wars gets too much flak, I won't deny that it had some lesser parts in the prequels and later games, but I still enjoyed watching all 6 movies and playing games like Knights of the Old Republic ( <3 ), Battlefront, Rogue Squadron, Star Wars: Bounty Hunter (Please make 1313 work LA, please, please, please).
C: While Halo is certainly a lot more expansive than "just some shooter games", it's not RPG like even though the Universe could lend itself to that, maybe a ODST 2 with RPG elements in a truly expansive planet with packed cities would be nice, but that's for game-designers to decide.
D: Enjoy both Universes bitches, enjoy em both.
