Super Metroid is a lot like Cap'n Jazz: they dropped a really influential LP in the late 90s, and everybody loved it so much that dozens of people built careers around ripping it off. Every once in a while though, something comes along that truly seems "influenced by" rather than "stealing everything that isn't nailed down from" their respective ancestors: Environmental Station Alpha is once such case. It's spooky, and looks nice; it's got stellar mechanics and a cohesive world. ESA changes enough from the Metroid formula to feel fresh, but it just absolutely nails the alien experience that makes playing and exploring the gameworld so compelling. I may even be doing ESA a disservice by mentioning Super Metroid so often, because it can stand on its own legs among classic games: Environmental Station Alpha is just great.
