You have the answer: Skyrim.Jang said:Skyrim. That kind of thing. Now, of course, these games are not particularly dark or complex by our standards, but to my girlfriend I am fairly certain it would be different.
Thanks in advance.
If you're worried about complexity or difficulty, have her start on Casual and work up difficulties as she gets used to the game.
For a non-gamer, Skyrim is very open and inviting. She will never be forced to follow the main quest and can instead follow whatever quests or side plots interest her. With the ability to adjust difficulty, there won't be any artificial skill walls to overcome.
