One of Minecraft's more remarkable side-effects is how it gave rise to (or, indeed, popularised) an entirely new genre: the survival game. Steam is absolutely packed with survival games, many of them unfinished and a surprising number of them pretty damn good regardless. Tough and uncompromising wilderness survival sims like The Long Dark and The Forest sit alongside slightly more off-kilter projects such as the quirky Don't Starve or the dinosaur-obsessed ARK: Survival Evolved.
