Play It?
I played both, and I would recommend Skyrim. There is simply much more you can do in it.
Skyrim. There's tons more gameplay and has the ability to generate an unlimited amount of quests.
as long as you have 2gb of ram, which is how much Bethesda have restricted Skyrim to use on any computer ( without the use of a mod), you should be able to run Skyrim, mediocrely
Any that suits your playstyle.
It should tell you if you need to update
Both. Skyrim has more modern graphics and mechanics, is longer and is less repetative, but playing Oblivion adds another layer of depth to the world of Skyrim. For example, Margret is visiting Skyrim from Cyrodil, the main location in Oblivion, and simply knowing about the location where she comes from makes it more enjoyable. If you can only play 1, then make it Skyrim.
Use a Khajiit, they are good at sneaking.
Dark Elf, Khajit or Argonian
