Oh sorry I didn’t explain myself well enough. I mean if there’s a significant online component where a large part of the content is interactions with other players, it seems like there’s a shelf life to getting the best experience from the game. So maybe it’s worth having a legit copy instead of pirating some time down the road.
You’re not missing anything content-wise if you play it solo. In solo mode you control all 4 of your party members during their turns, and in the multiplayer mode you control some of your party and your friend(s) control the others. The game content is the same but the experience is very different since multiple players are generally less tactically coordinated than a single person and they can wander the map separately
dunno what the policy for pirating is here, but https://gog-games.to/ you can find a “test” version on here
