Vagrus - The Riven Realms is a narrative-heavy RPG about trading and surviving in a post-apocalyptic fantasy world. You lead a caravan of people from city to city, encountering events along the way and managing your supplies, morale, and other indicators. There are a lot and lot of stats and knobs to turn for both your entire caravan as well as individual, more important members of it, yourself included. Death and disaster are ever-present, and there will be a lot of setbacks.
The game is focused significantly more on making decisions than fighting battles. In fact, the combat system is rather small and boring. While I definitely wouldn't call the decision-making side of the game small, I would still call it boring. Behind the large complexity of things to do, there doesn't seem to be a lot depth to it all. And this ties back to the game being heavily focused on the narrative, not the gameplay. From a story point of view, there are definitely a lot of different options to choose from, especially when it comes to the frequent and lengthy dialogue.
While reading everything is not necessary, I'm afraid it's the main virtue this game has. The worldbuilding is good, and I personally don't dislike the writing, but I can't say that at least the beginning of the overall story gripped me. Definitely not enough to keep me from leaving, but less picky people might enjoy it, especially on easy mode. But this is still a game, not a choose-your-own-adventure book, so much of the time is not spent on reading, but making these choices, which I found quite menial.
In the end, I don't like this kind of game. I'm pretty sure I could find many books in a similar setting with better writing and less forced interruptions to have to make decisions I don't care for. If you take out all the story, all the decisions you might make for roleplaying purposes, and just leave cold hard strategy, there isn't much to this game. A lot of boring decisions, leading to boring events. I think that even among games that try to blend worldbuilding, storytelling, and RPG / management elements, there are better options out there, so I can not recommend playing Vagrus.
