can you make alternative start saves for roleplaying
Yeah, as long as it is possible within the confines of console commands.
-spawning static objects (buildings, statues, walls) (I don't mod other people's saves for these as they take too long getting everything
just right)
-renaming NPCs (depending on if you want a custom name, it may take a while as I would then have to load the Creation Kit, and then create a plugin with the name and the CK takes a while to load on my POS laptop; same thing applies to renaming cells)
-renaming Cells
-Modded Skills/Stats/Perks
-Unlocked spells
-any NPC/creature as follower
-access to every item within the game
-Ending/Starting/Skipping quests
-Creating new items with interesting enchantments (as long as the enchantments exist)
-Alternate playable races (like Snow Elf if you have Dawnguard)
-For Hearthfire, any child to be adoptable
There's more, I just can't think of everything at the moment
