I'm not terribly invested in the Persona universe. I only played a bit of Persona 4 and that's it, but I like the art style of Persona 5 and would like to play it. Right now it's on sale for 34,99 € here in Europe, and for 49,99 € they're also offering the Ultimate Edition at a discount. As far as I understand the things that come with the Ultimate Edition are costumes and personas from older games as well as a new difficulty, a healing item set, a skill card set and (strange thing to unlock for money) the japanese voices. If it was extra missions or something like that I would go for the Ultimate Edition, but this seems more like fan service.
So, to those of you who have played it: Am I missing out on anything important/worthwhile if I just grab the Standard Edition?
