Marginal recommendation, and only at discount prices.
I really enjoy the flavor of the setting and the ability to play according to a variety of motivations (gold-obsessed conqueror, religious evangelist, pacific explorer, etc). You also have a lot of room to customize your team, which is much larger than a typical RPG party and gives you a lot of flexibility. Upgrades offer customization but in general there are some obviously-superior options and others that you'd never take in a million years.
The story lags a bit towards the end if you've clear-cut the map, and the end-game is a bit anticlimactic - you have potentially changed the geopolitical landscape and it just doesn't register as deeply as it should. However, there is a wide array of stuff to find, and if you are someone who *doesn't* try to find everything, then you will probably finish the game well before it overstays its welcome.
Significant downsides are that the gameplay gets very repetitive, and mechanics are clunky. At times this feels like a video game about text-based, micro-managed camping and foraging, which is not exciting. Movement is a slog, and the camera angles are locked in so tightly that it makes long-distance travel require a lot of scrolling back and forth on the screen. Combat is pretty weak and can be laborious.
The story and setting are great, though, the developers are mining very thought-provoking and educational territory, and those are what rescue this from a thumb down. However, for any spinoffs, they really need to upgrade the mechanics and gameplay, they are serious liabilities, and they got old quickly.
Bring at least 2 Doctors, you can get random events that leave a team member injured, and you could probably get stuck in a tough spot if this was either right after or right before a difficult fight that sidelined your best fighters.
Sword/shield is a great general skill for everyone, including Doctors - you can passively block a lot of damage with a shield!
I never deployed a Scout or Scholar in combat and it went just fine. Usually I went 1 Doctor, 2 Ranged, and the rest Melee. If I remember correctly there were a small number of fights with 4 team members and I either went 1 or 0 Ranged in the crew (but ALWAYS a Doctor). I preferred Sword/Shield by a wide margin, but I had a few Pike-based fighters because they were philosophically compatible, and because one was an Amazon (and they are mobile widowmakers).
Oh yeah, make sure when you pick your team at the beginning that you don't mix and match too many party members with conflicting philosophies, unless you want to manage dissent and mutiny.
