I've been trying for ages to mod my Skyrim to make it realistic, gritty, and of course insanely tough but I have way more mods than I can handle and merging and fixing and sorting all of them has proven fruitless as Skyrim either crashes or some mods won't be active (most annoyingly Alternate Start) and I'm done trying to merge mods....but I can't decide which mods out of my whole list would make the best gritty tough Skyrim with tons of monsters and quests to keep my character busy and possibly dead. So could someone look through my mod list and see which mods would make Skyrim the tough and gritty world that it should be?
