All late goin through FF7 rebirth and just did those fort condor mini-games...

I dont know myself yet. I think these ones where the party get shrunk down into the game gets that protorelic thingamabob, but I don't even know what those are for in general. (Or if rebirth has those fort condor games where you just play other people like in the yuffie dlc).

Other than that, just more party lvl exp. (Also hoping a new weapon/materia/something comes out of this).
