Cons ❌

1. Outdated for latest mods – Many cutting-edge mods (e.g., some DLL-based physics or modern combat frameworks) now require 1.6.1170 (late 2023+). You’ll be locked out of bleeding-edge stuff.
2. Downgrading hassle – If your Steam auto-updated past 1.6.640, you must use the “Downgrade Patcher” (Unofficial Skyrim SE Downgrader) – which can break Steam integration.
3. SKSE version confusion – Some mods list “SE 1.6.640” as “AE” (misleading), causing users to download wrong SKSE plugins. Double-check file names.
4. Missing ESL improvements – Later versions expanded ESL support for more light plugins; with 1.6.640, you’re limited to 4096 ESLs (still fine for most users).
5. No longer updated – Bethesda has moved on; if a mod requires a newer runtime feature, you’re stuck.
