I can't really tell you how much I can agree with you here. I've done some extensive reskinning of Peragus this week, and would like to get into more gameplay side mods. Yet most questions are either ignored, or the answers are long since lost or buried.
The current reskins are at 256x or 512x resolutions and really only darken the pre existing textures. Im bumping most up to 2k or 4k with customized textures. Looks nicer, and it is the start to a larger peragus mod i'd like to venture into.
