Skyrim is incredibly addictive and fun!

You don't have to tell me that.
Last night I wanted to play for 1-2 hours before sleep. Left Whiterun to go to the Greybeards.
On the way there I've explored 4 dungeons, killed 4 dragons and learned 3 shouts.
And this is only half the journey, because after this adventure I found out that the clock was pointing at 4:30 AM. Suffice to say... I got to work 2 hours late.

After playing around 20 hours with Special Edition I have to say that I enjoy it the same.
Even if the new lighting is not very different in the comparison screenshots, in-game looks really good in some locations.

There are also a few minor improvements that I found out that are not immediately obvious:
Now rain drops don't go through various objects. Previously rain would fall through roofs or under bridges, now it doesn't anymore. Small change, but lovely, especially if you use the "Frostfall" and "Wet and Cold" mods.

Also, now water flows more naturally through rivers. It changes direction and speed based on land shape. Before, water always was flowing in the same direction, no matter how the river was shaped. Sometimes even sideways.

Also, it seems there's a lot more grass now, without dropping my framerates into the gutter.

They fixed absolutely nothing in the Special Edition. You still need the Unofficial Skyrim Patch (SE version).
The only difference in SE Edition is that the game executable is now 64bit (which allows for more memory, more mods), some new shaders and somewhat better lighting.
Oh, they've also upscaled the original textures from 1k to 2k, without even modifying them. What that means is that the game now uses twice more video memory while looking exactly the same. Good job on that.

Good thing is that it's free, because I can't imagine the shit show it would have ensued if this would have been sold again, even with a discount.
