The entire SteamWorld franchise is one big flex. Almost every game dabbles in a new genre, bending and contorting it to fit the western robot-punk, vaguely post-apocalyptic aesthetic — but bringing with it some quality of life changes or spins on well-trodden formulas that feel completely unique. It’s never quite as simple as just slapping robots into a game you’ve already played before.

SteamWorld Build plants a flag in the ground of the land of city-builders with the lovely added depth of allowing players to burrow into the caverns beneath to extract the valuable elements and resources needed to continue expanding your soon-to-be metropolis. This feels in the moment like you’re playing multiple games simultaneously: Build your city until the balance of resources starts to skew into the red, then tunnel into the cavernous maw beneath to find new veins of ore to mine. Eventually, you’ll have cleared out as much of the underground as possible which sends you back up to the city to expand its reach and the inhabitants who live there as some will invent new tech for your mine shaft.

In this way, Build creates an impossibly sticky loop. Every action is rewarding, and every action feeds into another future action. As your city and mining operations each grow, they grow the possibility-space one plays within until you find yourself red-eyed and hunched, hungry and unclear of the time. Eventually you’ll need to just smash the eject button and go to bed.
