Starbound vs The Blockheads
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.
The Blockheads
The Blockheads is the game to play if you want to play a sandbox/survival game that's almost the same as Minecraft but with a whole lot more crafting.Featuring an isometric 2D look, the Blockheads is a game where you can venture off into the world to explore and possibly discover hidden treasures. You can also collect blocks, craft, and build almost everything you can see in the game through the game's many upgradable workbenches. The game even allows you to go fishing and open a shop so you can sell your wares. However, like Minecraft, there are dangers lurking at every corner so you may need to be vigilant and get a weapon as soon as you can.
Interestingly, unlike Minecraft, you actually need to take care of your Blockhead. This means making sure he or she gets enough rest or they will perform the actions you ask of them at a much slower speed. There are also hunger and happiness levels so be sure you keep an eye on that.
