Kenshi vs Starbound
Kenshi
Kenshi is an open world, semi-sandbox, party-based RPG that offers players an completely open-ended gameplay rather than opting to force players to go through a storyline. You can be anyone you like in this game, be it an honest trader, an adventurer, a bandit or others. Scavenge important resources, including weapons and armor, from corpses and use them for your own. Recruit new companions from towns, build an outpost of your own, and grow it to accomodate more of your companions. Of course, as your little town thrives, bandits and jealous rivals will attack you and you'll need to make sure all your people have what they need to defend the town and repel the invaders.Sounds like fun? Well, it definitely is. However, Kenshi, being a pretty ambitious early access game, does have it fair share of flaws. The game still has plenty of glitches still and can be really hard to get into, especially at the beginning of the game where you literally have no idea what you need to do.
That said, the game is very unique because it has a pretty rare theme and its gameplay - a combination of party-based survival/ base building - is also oddly rare among the other games on the market. So, you might want to check this game out.
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.
