I recently bought the  new Skyrim Legendary edition bundle on Steam  it’s about the same  price as the game was at launch but  includes the three DLC expansions. Dawnguard, Hearthfire, and Drgonborn. Previously I had  only played the base game on my xbox 360. The expsnisons add some pretty awesoem content! I love the house builfing from Heartfire and the Wearwolf and Vampire leveling abilities from Dawnguard.
One really awesome thing about  playing on on the PC is the community mods that are available. Everything from more  attractive followers to whole need content areas and  unofficial bug patched. A great site for finding mods is Skyrim Nexus https://skyrim.nexusmods.com that even have  a mod installer tool that works pretty slick! The only trick is you need to  make sure you get the  mod load order right or it will give you some frustrating bugs!
