Items in the Creation Club store have been curated by Bethesda, and are all compatible with each other, meaning installing one won't cause another to become unusable.
In a sense, Creation Club content is a step above the average mod, but doesn't quite attain DLC status. The Creation Club launched in 2017, offering a less-than-official means for Bethesda to add fan-created content to both Skyrim and Fallout 4. For the game's 10th anniversary, Skyrim Anniversary Edition will add a wide variety of content from Bethesda's Creation Club program. The open world RPG has had incredible staying power in an ever-evolving games industry since 2011, being released on nearly every platform possible.
It's been 10 years since the release of The Elder Scrolls V: Skyrim, and with TES VI still years away, Bethesda has decided to release yet another version of Skyrim with even more features.
