Skyrim has always had amazing vistas to take in and while they're mostly the same here in the Special Edition, there's a definite feeling of there being more here. The biggest beneficiary of the special edition treatment is the game's lighting systems which stand out, especially when the game is played on maxed out settings. Instead, with Skyrim: Special Edition, the devil and thus the value is definitely in the details. Be warned though, that difference can be hard to notice at first since Skyrim doesn't go for the sweeping overhaul that many remastered games do these days and many fans were hoping for.
A side by side comparison though proves just how much of difference this version is from the last.
To be fair, I didn't really think Skyrim needed a fancy special edition remaster as my memories of my time running through the forests of mountain peaks of Bethesda's masterpiece are pretty similar to the overhauled visuals, especially when combined with the huge amount of user created mods currently available for the game.
