The Elder Scrolls V : Skyrim

Another fun game is the latest saga in The Elder Scrolls series - Skyrim.  It's a great game to show off what makes a PC so great - customization and modding.  Already there is a huge collection of mods and texture packs for Skyrim.  

A couple of good places to get mods and textures packs are Skyrim Nexus and Fileplanet.  You will need a small program to extract the compressed .lz format files.  I can recommend 7-Zip, an open source software program that does a great job.
