If you're like me, your run your PC Skyrim with like 100 mods, at all times. Out of all of them, which do you think are the most essential? For me, I would have to say... Realistic Needs and Diseases - Exactly what it says on the tin. Basically, like nightmare mode from Fallout: New Vegas. You have to regular eat, drink and sleep in order to stay alive. Food can spoil, you can get drunk, and you can catch diseases from eating raw or stale food. It adds a lot of additional challenge to the game, which I like. Skyrim's Unique Treasures - Adds a bunch of random unique treasures into the world. I always was kind of annoyed how, in Skyrim, you'd loot some ancient chest, just to find your standard gold and gems. By adding all of these unique treasures, the game feels a lot more real.
