I don't think there are really that many games that actually have a prerequisite of understanding video game concepts. Any game taken on its own can probably be figured out by someone who hasn't played any video games before with enough perseverance.
When I was 16 I showed my step mom FFX and tried to explain how the game worked, what she should be doing, etc. It was all a giant ball of confusion for her and she gave up before getting out of Zanarkand. I think there's a lot of games like that!
