I don't mean this like a Facebook game. I mean you literally need to find characters in-game (who each represent one of the Tarot, which are how Persona are divided up), get to know them over time, help them with their issues, and by doing so you rank up your "Social Link" with them, which represents how well you understand that person.
For instance, if you spend time with Yosuke after school, you'll learn what his life is like as the son of the manager at the big chain store that is basically destroying Inabe's main street stores. By doing this you rank up your Magician Social Link, which gives Magician-type monsters extra XP when they are fused. At max level you can summon the ultimate Persona of the Magician group. It also makes Yosuke a better fighter, giving him new abilities over time like taking a fatal hit in your stead, performing a follow-up attack on downed enemies, and eventually upgrading his Persona into a stronger form that doesn't have an elemental weakness.
This is all on top of the normal RPG dungeon aspect that you do in order to save the murder victim of that month (which can you do in the afternoon instead of working on your social links or working a job).[DOUBLEPOST=1353481479][/DOUBLEPOST]
Cool, cool. So in the Persona games, some people who kill themselves get Personas right? I just find it funny because this along with Akira are two Japanese franchises that involve getting super-powers through less than reputable behavior.
No, not at all. Personas are a natural reflection of a human's Will over it's Shadow (think Jungian dream theory). Not everyone can use them though... they usually need some means of manifesting them. In Persona 3 they do this with technology, using Invoker guns that basically fire psychological trauma into someone's brain to bring them out (I have NO IDEA how this works). In Persona 4, the power to use a Persona comes from confronting one's own Shadow in the TV World and accepting that they are a real part of your personality. No matter how you do it, you only get to summon a single, unchanging Persona unless your self-identity changes.
The people who are exempted from this are the main characters, who are "wild cards", which allows them to summon multiple Persona. This is because of quirks involved with how they were exposed to the power of Persona to begin with... which I won't go into because of SPOILERS.
