Also, you may have noticed that the NPCs featured in my screenshots so far are (mostly) randomly chosen. I think it could be interesting to have a picture comparing how the major replacers handle prominent characters from Morrowind, Tribunal and Bloodmoon main quests. If not key-NPCs, at least characters that every player is bond to meet in the course of his adventures.
Excellent idea. May I suggest a couple of characters from each of the major factions involved in the main quest?
Temple: Mehra Milo, Archcanon Saryoni (Vivec)
Hlaalu: Crassius Curio (Vivec), Orvas Dren (Dren Plantation)
Redoran: Athyn Sarethi, Bolvyn Venim (Ald'ruhn)
Telvanni: Master Aryon (Tel Vos), Divayth Fyr (Tel Fyr)
Ashlanders: Nibani Maesa, Sul-Matuul (Urshilaku camp)
Imperial guilds: Hasphat Antabolis (Balmora), Sharn gra-Muzgob (Balmora)
(That's just Morrowind, by the way; I'll let someone else tackle Bloodmoon and Tribunal.)
