I’d go with Skyrim on the PC. On the Xbox 360 version, my rogue-style character is level 40, and I’m 130 hours in - and the end still seems to be nowhere in sight. When the Steam holiday sale hit, I also purchased Skyrim for the PC. A couple of weekends ago, I downloaded the enhanced high-res textures and a bunch of other highly recommended mods from Skyrim Nexus and the Steam Workshop. After firing up the game, I was completely blown away by how incredible it looked (compared to the 360 version), and by how much the mods enhance the game that I’m already addicted to. So, If I had an entire day to play something, I’d start an all-new magic-based character on the PC version of Skyrim!
