What is more realistic and why: Minecraft or Skyrim?

Skyrim, in minecraft there's floating trees and you can carry 64x36 cobblestone blocks in your pocket…

Skyrim my man! It's so cool! Too bad my PC won't support it anymore.

But this is only realistic in terms of adventure, not personal life. I even tried going from Riften to Solitude by WALK! Ahh what an amazing three days (Skyrim time) adventure there.

Skyrim is more realistic visually, but Minecraft is more realistic in the adventure sense. What I mean is Skyrim has amazing graphics but, you are limited to what you can do, where as in Minecraft you can break most blocks and build anything.
