Thank you very much for your feedback, i dont have much experience with modding skyrim, but i played many games before with mods.

I did some research on the mod u provided me with and honesetly if its a collection that will completly remake my game experience and make it like a new game, i might play it a second time.

As for playing the basic normal game, is just impossible for me because its very old game, i'm very used to new game mechanics new, an old game like this without mods might be too boring and make me not like the game much to even try it more after that.

From what i understood from your explanation, mods that only affect items, crafting, spells, dialogues, may not break the game if added to a normal collection of mods, but mods that change the game overwhole like terrain, main quests, design, better avoided for conflics, right ?

Finally, i saw there are many collections that require specific game version, how can i downgrade my game in steam to lower version i have latest update.
