Terraria, at least above ground, is the epitome of PC gaming peacefulness. The sun shines. The plants grow. The goal, essentially, is to build for yourself the most serene, rural life possible, albeit occasionally disturbed by nightmarish Lovecraftian demons. But let’s take that tranquil, typical Terraria existence and add a little chaos. Inspired by the slapstick, physics-based comedy of building and strategy sim Kerbal Space Program, a new, cozy farming game, available on Steam, feels like Terraria and Stardew Valley, except sometimes the crops explode. This is Southfield, a colony and management game where the gravitational rules of the universe are out to get you.
