The AE in core itself is free (comes with 3 CC mods), so it'll be an autoupdate. Thousands of functions are changed or deleted.
It's a separate game, like Skyrim LE and SE are. What does this mean to PC players who mod SE: Only players to consider it are PS4 players who have utterly limited modding capabilities thanks to Sony being Sony. It's the same Skyrim SE, just with some CC content inbuilt (Creation Club, Bethesda's own mostly paid mods, all of which have free, and often better, analogues). It's called (surprise) Skyrim Anniversary Edition.
👉👉 Important warning to everyone who mods Skyrim SE 👈👈īethesda did it again - they re-release same Skyrim at.
