The setting itself is a fantasy built into the vacuum of a collapsed great empire, the main protagonists are people fleeing their old lands which were corrupted by death. The themes are environmental, primal and elemental. Much iconography and mood feels drawn from old myths and stories like the Edda and the Kalevala. The wild is unknowable and dangerous, corrupting and vigilant. The forces of the world are driven by powers that mere mortals do not, and perhaps can never understand.
The artistic style carries through into the muted tones of the maps and book, naturalistic colours dominate the palette. The history and setting match the visual style beautifully, and while the tropes common to fantasy are present, they hearken back to their primal roots more than they lean on modern variations. Elves and trolls, wild beasts and dragons, all are there in plenty if you venture into the forest deep enough, but they are not the elves and trolls of the Lord of the Rings, nor those more modern versions typified by Dungeons and Dragons or Warhammer. They are the elves of folklore, elemental and fay, wild and dangerous. Dragons will as soon manipulate, fool and trick as they will roar with fury and power. There is much to like in this setting.
The rules are light and easy, encounters dangerous and over quickly, even between powerful adversaries. Special abilities allow characters unique talents that can be fun and interesting when employed well, and provide lots of ways to substitute one stat for another, meaning combat doesn't need to be the exclusive province of the stereotypical tank. It is possible to game the system to some extent, and GMs and players alike need occasionally to be ready to make a best judgement and move on. But it is an engaging and quick moving game engine that allows heroic action and story to come before the minutia that dominates many game systems.
I won't go much further in detailing the mechanisms and setting, Symbaroum is a game with an evocative and stylized world. A setting that is challenging, dark and fay. The rules are relatively simple, roll a D20 and get below your modified stat. One of the more unique elements is that only the players ever touch the dice: they roll for the damage they inflict while enemy armour simply soaks X, they roll their armour while enemy attacks simply inflict X. It is a system that took a game or two to get used to, but works, and works quickly and well. This is a game I have thoroughly enjoyed, and while we're only around 8 sessions in, I am looking forward to playing more.
As of writing this J rnringen are running a Kickstarter for their version of a Monster Manual. It looks great. If you're interested at all in the game - I'd recommend checking it out!
I should note - while I freelance for Modiphius I have never worked on the Symbaroum line (though of course, it would be awesome to do so), I am recommending this game purely as a fan.
