Sea of Conquest Review: Is it worth your time?

Games Like Sea of Conquest: The wider genre.

Beginner's Guide: If you have decided to play.

Quick Answer

If you have seen both games and thought they look like the same game with a different logo — you are not imagining it. Players consistently report Reign of Pirates as being effectively the same product as Sea of Conquest under a different publisher: the same flagship-and-cabins structure, the same hero-crewing system, the same art direction and interface.

We have not been able to verify this from any official statement, and neither publisher appears to have commented, so treat it as a widely-repeated player observation rather than a confirmed fact.

Practical answer: whichever one you install, the guides on this site apply to both, because the systems are the same. Pick based on server age and which one your friends play, not on features.

Why They Look Identical

Re-skinning and licensed regional variants are common in mobile strategy publishing. A studio builds an engine and a game loop, then it appears under several names across different markets and publishers.

What players report seeing in both:

A flagship as the central base, upgraded in levels
Cabins inside the flagship handling production, combat and crafting
Heroes crewing ships in captain and support slots
A cooking and distilling economy feeding gold and events
Seasonal map resets and alliance territory

If that list matches what you are looking at, everything on this handbook applies — the beginner's guide, the recipes tables and the flagship requirements included, with the caveat that a variant may have rebalanced specific numbers.

Where They Genuinely Differ

Even between identical builds, these vary and they matter more than features:

Server age and population. The single most important difference. A fresh server means you compete with people at your stage; a two-year-old server means you are farm for established alliances. Check when servers opened before installing either.

Player base and language. Different publishers serve different regions, so alliance chat, time zones and rally scheduling differ substantially. A game where every war window fires at 4am your time is a worse game regardless of its systems.

Event cadence and collabs. Sea of Conquest runs documented crossovers — KOF XV in 2025, Fist of the North Star in 2026 — see the hero tier list. A variant may run different ones or none.

Monetisation specifics. Pack contents and pricing are set per publisher — see the top up guide.

Codes do not transfer. Gift codes are issued per game. A Sea of Conquest code will not work in another title, which is a frequent cause of "this code doesn't work" complaints on aggregator sites that mix the two.

Which Should You Play?

Play whichever has a newer server, or whichever your friends are on. Those two factors will affect your experience far more than any difference between the builds.

Do not play both simultaneously expecting to transfer progress. Accounts are entirely separate, and splitting your daily routine across two flagship build queues halves your progress in each.

If you are already invested in one, stay. There is nothing in the other worth restarting for.

Are They Actually the Same Company?

Sea of Conquest: Pirate War is published by FunPlus. Reign of Pirates appears under a different publisher. Whether that reflects licensing, a white-label arrangement, or something else is not something we can confirm from public sources.

What we can say is that the player-facing systems are reported as substantially the same, which is what matters if you are choosing between them or wondering whether your guides transfer.

FAQ
