Honestly, I kinda wish that Bethesda would do a new release of Skyrim that aims at playing well with massive mod sets. Like, slash load time for huge mod counts via defaulting to lazy-loading a lot more stuff. Help avoid or resolve mod conflicts. Let the game intelligently deal with texture resolutions; have mods just provide a single high-resolution image and let the game and scale down and apply GPU texture compression appropriate to a given system, rather than having the developers do tweaking at creation time. Improve multicore support (Starfield has already done that, so they’ve already done the technical work).
