Most strategy games treat diplomacy as a convenience or after thought. You build an army, attack, and if diplomacy exists at all, it's a side feature you can safely ignore. Solium Infernum flips that completely. Diplomacy is the battlefield, and your army is just an instrument you're only allowed to use once you've fabricated the right excuse.

Satan's gone, the throne of Hell is empty, and you're one of several Archfiends trying to get elected by the Infernal Conclave. Whoever has the most Prestige at the end wins. What makes this work so well is that Prestige is simultaneously your victory condition and your currency for doing anything meaningful. Spending it to attack someone weakens your position in the race. Hoarding it paints a target on your back. The game produces this constant tension organically, with no artificial catch-up mechanics needed.

You can't just declare war whenever you feel like it. You need to manufacture a diplomatic incident first. You insult someone in front of the Conclave, you demand tribute, you send emissaries. If the other player refuses your demand, you get to declare a vendetta, a limited war with a specific objective, a time limit and a Prestige wager. If they keep ceding to your demands, you can declare them weak and attack anyway. Every diplomatic tool has a counter, and every counter has a cost. It's an intricate dance where you're always weighing risk against reward, and the information you don't have matters as much as the information you do.

Because that's the other thing Solium gets right: imperfect information. You don't know what relics your opponents chose. You don't know their secret schemes. You don't know how much tribute they've stockpiled. You see the Prestige scoreboard and the legions on the map, and you have to infer the rest. This turns every interaction into a poker game. When someone insults you, you need to figure out whether they actually want the vendetta or they're bluffing because they expect you to fold.

The Bazaar is another clever system. Items show up and all players bid secretly. You don't know who's competing for the same artifact. Sometimes you overpay for something mediocre because you suspect your rival needs it more than you do. Sometimes you lowball and get lucky. It's one more layer where hidden information creates genuine tension.

Each Archfiend plays in a fundamentally different way. This isn't a "+5% production" bonus situation. Belial lies and manipulates, Astaroth dominates militarily, Andromalius plays the vassal game and can steal the throne from under someone else's nose. The same rules produce qualitatively different matches depending on who's at the table.

What surprised me most is the narrative arc each game produces. Because matches are short, dense and full of reversals, every game tells a story. You were losing, you provoked a vendetta against the leader, you stole his Place of Power on the last turn, you won by two Prestige. That kind of thing happens naturally, without any scripting. The game just creates the conditions for it and gets out of the way.

The art deserves special mention. The map is draped in grays and blacks with splashes of red and gold, and the card art for legions, praetors and artifacts is genuinely striking. It commits to its hellish aesthetic fully and it pays off.

If you're tired of strategy games where the strongest army wins by default and diplomacy is an afterthought, this is the antidote. Solium Infernum treats strategy as a game of intellect and observation, where your ability to read people matters more than your ability to stack units. It's not for everyone, and the learning curve is real. But once it clicks, nothing else quite scratches this itch.

When I initially got this game I was kind of put off by the tutorial. Belial (one of the archfiends you can play as but also the guide during the tutorial) gives a pseudo exhaustive intro to the game that at times feels overwhelming. I put the game down about 20% of the way into the tutorial and didn't pick it back up for about 6 months. This time I persevered and I can honestly say that the game is very fun and pretty easy to understand once you get past the tutorial. I think this game is pretty underrated, and if you enjoy grand strategy or civ like games, this game is gonna be the right pick for you.
