I'd really like to see comparison shots of various lighting mods and ini tweaks. I don't remember enough of the vanilla game to really see how much it changes things when looking at a random shot of, for example, Balmora with a mod in place. It's nice to be able to see how much one mod differs from another as well as an untweaked Morrowind.
Ideally I'd like to see this done without MGE and retextures, as I can never tell how much of it is a lighting mod and how much of it is a shader/texture.
