I'm thinking about getting my Wife the Vita and had 3 Questions about it.

1. Do you have to use a security token to log in, or do you have to be signed into the game on the PS4 then start remote play?

2. what are pro's and con's of using remote play?

3. Can it play FFXIV like the PS4 (understandable if the resolution isn't as high) or would there be some technical restrictions.
