Stellaris and Crusader Kings 3 Dev Paradox Teases it’s Next Big Grand Strategy Game — And Fans Think They’ve Worked Out What It Is

Stellaris and Crusader Kings 3 developer Paradox Interactive has something “ambitious” to show us next week.

While the team stopped short of showing any concrete details at all, it did remind us that Paradox has been developing and publishing strategy games over the last 25 years “that have taken you from the Roman Empire to the stars,” and teased it was now “preparing to announce the next major title in the genre.”

The mysterious new game — known only by its codename, Caesar — has been openly discussed on the studio’s forum in a number of “Tinto Talks” developer diaries. Over this time, it has been welcoming community feedback on its feature ideas, key game systems, and historical research, but “now the time has come to reveal Ceasar to the world.”

The latest Tinto Talks — named after the studio that’s developing it, Barcelona-based Studio Tinto — talked about the mechanics of Protestant religions and the “final situation involving all Western Christian confessions, the War of Religions,” coming to its “entirely super-top-secret game with the codename Project Caesar.”

That, plus the clue that the announcement video will premier on the official Europa Universalis YouTube channel, suggests the mysterious project may be a new addition to that series… but nothing’s certain right now.

That hasn’t stopped fans speculating, though, with many coming to the same conclusion that it’s probably connected to Europa Universalis, too.

“Dev Diaries haven’t called it EU5 but everything we have been teased thus far heavily implies it,” reminded one player on Reddit. Another, replying to someone else pointing out that the video will debut on the Europa Universalis channel, teased: “There might’ve been clues along the way huh.”

“I mean, it was an open secret for over a year thanks to the Tinto Talks Threads on Paradox forums,” explained someone else.

To find out more, and discover if the rumors are right, tune in to Paradox’s video at 9am PDT (12pm EDT, 5pm UK time) on May 8, 2025, and discover “a new era for grand strategy.”

We had a great time with the last Europa Universalis game, awarding it 8.9/10 in IGN’s Europa Universalis 4 review, saying: “Europa Universalis IV brings accessibility and flexibility to the strategy series without compromising its complexity.”
