Everywhere!

Standing next to the statue of Tiber Septim overlooking Windhelm was pretty cool. Riverwood is also great, I agree. But what mods improve it?

The hot springs, the swamp, the frozen sea...

I see a lot of you have mentioned Riverwood, I completely forgot about it while creating this thread I must admit it looks beautiful. It really helps you appreciate how good the world looks straight after you escape Helgen.

The Talos shrines. They are usually in remote places, high up in the mountains or in hidden valleys, and there's something thrilling about rounding a corner and finding one. It's also moving to see what people left there, given that they're risking their lives to do so.

Riverwood is my villa and Solitude my home.

Sort of like the balcony overlooking the water from Honeyside in Riften. Pity the game doesn't seem to include working fishing-rods this time around.

That would be awesome, just chilling up on your balcony catching your dinner!
