One subject a friend and I had been discussing a few weeks back was regarding the atmosphere during the confrontation with the Jedi Council in the rebuilt Enclave. as you guys know the music score in the Jedi Enclave with the council and Kreia has to be one of the most beautiful yet sad soundtracks in KOTOR2, Anyway my friend and I don't really feel the sunny weather fits the scene or it's soundtrack and wondered what it would be like were it raining lightly with gray rainclouds floating overhead, in a sense we believe it would add a dreary atmosphere to the ruins of the Enclave and remembering what happened to Jedi in this place would cut all the deeper as far as some of we light sided players are concerned.
I have no modding experience and honestly I don't even know if such a thing could be pulled off, but I thought I'd throw the idea out there anyway.
