If you can teach me how to Play Oblivion without my enemies becoming ungodly stronger than me whilst not making it a mess of confusing formulas, i'll perfer Oblivion.
Just find something you like, and focus on it.
Thats the biggest thing.
I like stealth, so I focus on stealth.
I will say though, Skyrim is easy as hell but the kills are more satisfying. Because of the finishers.
