Don't Starve vs Starbound
Don't Starve
Don't Starve is a pretty dreary and dark survival game set in a rich world filled with plenty of animals/game to hunt, monsters to kill, and resources to gather. With a gothic-like theme, the game's best feature is perhaps the way it hands the reins to its players and let these players decide what sort of survival game they'd want to play and how difficult will the game be. You can literally customize everything in the world you'll be playing in, ranging from the weather, how frequent lightning strikes, how long a season lasts, how much resources are spawned and many more.The game also has a very nice selection of characters that you can gradually unlock as you play the game. Each character will even have their own specialty that you can then make use of when the situation calls for it.
Don't Starve is a survival game that's as punishing as it is vicious. Expect to die a lot in the game and turn all those deaths into useful lessons that you can then build upon. If you fancy surviving with your friends in tow, then you might want to get the multiplayer version of the game, Don't Starve Together, instead.
Starbound
Starbound is amazingly fun 2D sandbox/exploration game that will put you in the shoes of a spacefarer and a captain of your very own spacecraft. As you travel through space, you will need to stop by planets to collect resources and perhaps even colonize them so you can also gather up a crew to man your ship. There are up to 7 races to play as, a story campaign where you are tasked to save the universe, and 3 different game modes ranging from Casual to Hardcore to either provide you with a fun relaxing experience or to put your survival skills to the test. You can even play the game cooperatively when you want. For modders, you can add in new races, biomes, dungeons, quests and anything else you'd like as well.Starbound can be turned into a pretty much an endless game due to its procedurally generated universe, where you can simply fly around in your spaceship looking for your next big adventure. Thus, you can definitely expect hours of gameplay at the very least for your first playthrough, making this game very well worth its price.
