Games Like Really Big Sky (2026)

Shared: Boss Rush, Score Attack

Gorgeous on the outside, brutally unforgiving underneath, Cuphead is the boss-rush couch co-op that will bond you with a friend or destroy that friendship entirely, probably both in the same session.

Shared: Boss Rush

Fourteen years old and still pulling all-nighters - if a 2D sandbox has ever consumed your sleep schedule, Terraria is probably the reason why.

Shared: Score Attack

Few games from 2012 still live rent-free in people's heads the way this one does. Brutal, precise, and stranger than it has any right to be.

Shared: Procedural Generation

A punishing roguelike action-platformer where every run tries to kill you faster than the last. Survive long enough and you might just become unstoppable.

Completely free, permanently complete, and built by one person responding to a YouTube dare. If you have 90 minutes and a friend with a Steam account, there is no excuse not to try Muck.
