Changed Stars is a space opera TTRPG about a universe where humanity tried to colonize the galaxy and got quickly set to rights by the other powers of space.

The PDF is 306 pages, with small, dense text in a professional layout. This is an old school style full featured TTRPG, and it packs in information and art and mechanics. Everything is bookmarked and hyperlinked, and it feels relatively easy to navigate.

Writing-wise, both the ideas and execution are solid. The text feels compellingly told, and the geopolitical situations it sets up feel chewy and interesting. Most of the conflict comes from humans falling back on old human atrocity-doing, and I think Changed Stars get a lot of mileage out of positioning us as the galaxy's work-in-progress disaster.

In terms of character creation, things are decently granular without being overcomplicated. There are four stats, twelve skills, quick and slow hp, and a decent spread of species to choose from. Classes are loose, and come with some attribute and skill bonuses, a couple feats, and a unique gimmick called an Edge Break where you can go all out in a specific way and then fall into a coma. To round things out there's a robust equipment section and a big chunky drones and vehicles chapter. Ships are quite detailed, and come with a wide range of things for crew to do in combat and while exploring, hitting a very gameable sweet spot in between "5e spelljammer" and "this game is now entirely about ships."

Mechanics-wise, Changed Stars uses a d6 pool. Sixes are hits, one hit is enough to succeed, additional hits can be used to "yes and" the success. Players have decent control over the dice with Edge, that same thing from the Edge Break I mentioned earlier. You can use it to nudge regular rolls too, taking smaller consequences in exchange for goosing the dice a little. Combat, survival, healing, and other tabletop staples are all at about the same level of complexity, but feel fully fleshed out.  Violence feels dangerous, and the consequences feel life threatening, but you can absolutely go loud and have a hero moment without dying.

For GMs, there's a huge worldbuilding section plus general advice, safety tools, a bestiary, and a starter scenario.

For visual readers, the art bumps tremendously. It's a mix of black and white and color, and it does a very necessary job of anchoring the descriptions in the text to something immediate and tangible. The xenofauana looks nice, and the playable species have a lot of charm to them.

I think the folks who might bounce off of this game are those who are looking for something mechanically simple. Changed Stars isn't complicated for the sake of being complicated, but I'd also say it's at about Shadowrun complexity level. A 4--6 player group that's been doing TTRPGs for a while should be able to tackle it with ease. 

Overall, I'm glad games like this are still being made. A GM who clicks with the setting can spin a robust tale inside Changed Stars' universe, and a group who plays in it will get to make detailed characters, get into space hijinks, and more than likely shoot their way out.
