I will most likely play Infinite Wealth first, but currently playing through 0 and plan to play the rest of the series before.
I bought Persona 3 Portable when they rereleased it, so I plan to play that one first, then may buy P3 Reload after I finish Persona 4, 5, and the sub games such as Strikers and Tactica. P3 reload should be pretty heavily discounted by the time I play it.
I dont have any real interest in GranBlue Fantasy.
