It turns out that the only platforms she has access to are XBox and PC, so this discussion ends up being mostly theoretical, alas. (But still an interesting one!)

Kingdom Hearts, that's an interesting question. I have to think that it's more fun for Final Fantasy fans than a way to introduce someone to the series, since the characters are so out of context. I did really love the first game, though. (The second was fun for me as a fan, but as far as gameplay goes I would be loath to recommend it.)
