Question 2

Is Petit Planet free? Cross-platform and cross-save explained

Accepted Answer

Yes — Petit Planet is a free download on every platform (PC via Epic Games Store or a direct client, iOS, Android), with optional in-app purchases in the miHoYo style. Cross-platform: the official announcements confirm the game runs on PC, iOS and Android with cross-platform account sync — your planet and progress follow your account between devices. The official launch notices will spell out the finer details (friend cross-play sessions, etc.), and we will update this page as they land. MiHoYo accounts are shared across the publisher’s titles, so if you already play a miHoYo / HoYoverse game you will use the same account system.

Question 4

Petit Planet vs Stardew Valley — how the cozy sims differ

Accepted Answer

Both are cozy life sims, but they are built differently: Price: Petit Planet is free to play with in-app purchases; Stardew Valley is a one-time premium purchase with no monetization. World: Petit Planet gives you an entire small planet — grid-free terrain, coastline and sky shaping with a sci-fi palette; Stardew is a fixed farm map with seasons. Multiplayer: Petit Planet launches with the Galactic Bazaar, a shared universe hub for trading and hangouts, plus cross-platform account sync; Stardew’s co-op is limited to a shared farm lobby. Systems: Stardew has deep RPG systems — combat, mining, marriage, community center — while Petit Planet focuses on building, collecting and light exploration in the Starsea. Platform: Petit Planet launches December 4, 2026 on PC, iOS and Android; Stardew is available now everywhere. In short: play Stardew for deep single-player farming RPG; play Petit Planet for a free, social, planet-building take on the genre. Both are lovely — see the Petit Planet Wiki for everything about the new one.
