Haven't played Radiata. If this is anything like Suikoden, then not all 108 characters will be battle-playable - some of them will add functionalities to your home base, which is usually also a military base, and the JRPG gameplay will occasionally be interspersed with some, like, military/ship battles, and some 1v1 duel minigames I think?

But I mean, it seems you have the gist of what it's about, probably moreso than many people if you've actually played the spinoff, so idk what else there is to say. Battles will use 6 party members and you'll get various co-op attacks depending on which party members you use, I think. Been ages since I played a Suikoden game.
