I just figured out I had Skyrim in my Steam games. It's the 32-bit non-Legendary Edition Skyrim without any DLCs. Can I still use Legendary Edition mods on it?
Yes, you can.
Mods developed for the original Skyrim, with or without DLC, will work fine on the Legendary Edition, which is essentially the same thing, but provided as a complete set of the base game and all DLC (similar to a Game of the Year edition). Or:
- Whatever mod requires Skyrim - with or without any additional DLC - will work with Skyrim Legendary Edition.
- Whatever mod requires Skyrim Legendary Edition will only work for a version of Skyrim with all DLC installed.
