Quite simply, I would call Suzerain more of an "experience" than a video game. As a fan of narrative adventures and text-heavy RPGs with serious choice and consequence (Disco Elysium, Pentiment, Torment: Tides of Numenera, Telltale Games, etc.) Suzerian far exceeded my expectations.
Never in a videogame have I agonized so much, and so often, over my decisions. The level of nuance and gray area contained in this game is almost overwhelming - your ideals WILL be compromised; your moral compass WILL be challenged; the 'right' way is rarely ever the 'best way'...
If you want to feel the emotional weight of running a developing, but unstable 2nd world nation - in the midst of greater international turmoil and maneuverings - Suzerain is absolutely a game not to miss.
