the self-entitlement and whiny attitude (not you) I've observed in some gamers are just astounding. The SE was given out for free. If they don't like it, don't play it. Just stick to the regular one with the existing mods if they don't like the SE.
Yeah; I don't get the entitlement, either.
It's very nice of Bethesda to do this + good publicity for them to just flat-out give SE to those who owned LE on Steam in the first place. This is great - I don't have to re-buy the game, if I want the new version b/c I already have it now. I can run SE without mods, if I like. I can wait for more mods to be ported or developed for SE, if I like. I can run Original Edition, if I like. I have hard-drive space - so I do have both installed right now. Hey, whatever floats the boat!
Certainly, SE does look + run better than the original edition (without mods). I think SE being on a 64-bit EXE makes a major difference, performance-wise. Now, I just need some a few mods ported or newly developed here and SE will be where it's at for me. I had no problem porting my saves from LE to SE, probably since I never majorly modded the original game's content much (mostly used UI stuff + Quickloot Mod).
In some other cases - i.e. Sleeping Dogs Definitive, Dead Island: Definitive + Dead Island Riptide: Definitive, Metro 2033 Redux, Metro LL Redux, etc - gamers who wanted the new overhauled version w/ new graphical stuff had to buy the new version, if they wanted it. Whether they were given a discount or not b/c they owned older versions...well, that's another story entirely.
If any gamers are thinking they should pass on Skyrim LE b/c it don't give you the extra free SE anymore, that's crazy talk - at $10, LE is a steal. LE packs so much content, it ain't even funny. Easily over 100 hours of content in LE.
