At first glance, it is easy to assume that Starbound is nothing more than a Terraria clone. Don't make its appearance fool you. Starbound takes things to a whole new level with its gameplay. You start off in the game with a damaged ship in need of repairs.
You beam down to the planet below to begin gathering resources to repair it. Once repaired, you are able to explore the vast infinite cosmos. You can land on various planets, creating anything you wish... or simply just explore. On your travels, you can capture monsters and train them to fight alongside you.
There are thousands of craftable items, three difficulty modes to suit everyone's play style, customizable space ships and seven different races to choose from. There is also a storyline to follow if you wish to do so. The biggest thing that separates it from Terraria is that it is fully moddable with Steam's Workshop, resulting in endless fun and possibilities.
