Scattered worlds were claimed on the fringe of the galaxy. Each pocket of survivors held on to an isolated set of worlds while trying to rebuild under the great law of Shalun. Three centuries later, technology has brought them back together again. Discovery of the hyperwarp has bridged what was once an unimaginable distance between far-flung colonies, long-lost families, and political factions. With that reunification has come great economic prosperity. The hyperwarp reestablished the transportation of cargo, goods, and technologies between the quadrants – but it has also brought great strife. Political rivalries have been rekindled, blood has been shed in age-old feuds, and the fires of war have been stoked. Amidst the political infighting, a ruthless revolution is rising – and the fervent explorers of the hyperwarp have awoken something that was better left asleep. Our very first game, Star Traders RPG, took hundreds of thousands of gamers on an interstellar adventure. Star Traders’ success and overwhelmingly positive reception helped to launch Trese Brothers Games. It was the adventures of our community’s star-crossed captains that put us on a trajectory to share more of our worlds, ideas, and dreams. We set out to capture the loneliness, bravery, and camaraderie of people living together in a spaceship sailing across the stars. It is with great pride that after releasing four other games in the Star Traders universe, we’ve created a sequel to the original Star Traders RPG. Step onto the bridge of your starship, take to the stars, and create your own story in Star Traders: Frontiers.

Verdict

The call

The clearest difference is ratings volume: Star Traders at 668 against Kairobotica's 13. Star Traders also leads on update cadence (every 3 weeks vs every 3 months) and chart position (#25 vs unranked). Kairobotica's advantage is review sentiment (84% vs 73%) and price ($4.99 vs $6.99). On rating, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Star Traders holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Star Traders has 668 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 84% of Kairobotica's written reviews are positive against 73% of Star Traders's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Kairobotica ships an update every 3 months, Star Traders every 3 weeks. The most recent releases landed on September 26, 2026 and September 24, 2026 respectively.
