Best open world crossplay games ranked by Steam interest
When you factor in Steam interest, Valheim, No Man’s Sky, Satisfactory and ARC Raiders stand out as the best open world crossplay games for PC‑heavy groups. Valheim’s dedicated servers and crossplay between Steam and the Microsoft ecosystem make it easy to keep a persistent world running.
No Man’s Sky continues to receive sizeable updates, which keeps its concurrent players healthy and its co‑op loops fresh for both new and returning squads. Satisfactory and ARC Raiders are more niche, but they rank well on Steam charts for open world or cross-platform tags, making them good options if your group wants factory building or extraction‑style co‑op instead of classic RPG leveling.

Valheim, No Man’s Sky and Satisfactory consistently show strong concurrent player numbers on Steam compared with smaller crossplay titles.
How to choose the best open world crossplay games for your group
Start with platforms: confirm that everyone can actually join the same lobby, then check whether crossplay covers PC store splits like Steam and other launchers. The next filter is session length; games like Grounded or Valheim work better when you can commit to multi‑hour base sessions, while Sea of Thieves or No Man’s Sky feel fine for shorter raids or exploration runs.
You can also think about skill gaps. Genshin Impact and No Man’s Sky let weaker players contribute through exploration and lighter combat, while ARC Raiders or Diablo 4 expect more focus on builds and dodging, similar to other action RPGs. If your friends often ask for sensitivity and FPS tips, point them to a broader settings hub for each game so they can tune their rigs before raid night.
What open world crossplay game is best for casual players?
Genshin Impact and No Man’s Sky are friendly starting points, with forgiving early zones and flexible co‑op that does not punish slower players.
