Sheltered vs Starve.io
Sheltered
Sheltered is, in some way, a mixture of the survival management gameplay that Fallout Shelter has popularized and the emotional rollercoaster that This War of Mine puts you through, all rolled into a single game. In this game, you play as the protector of a family of four who managed to make their way to a deserted shelter in a dreary, post-apocalyptic world. Like Fallout Shelter, you can plan, build and expand your bunker to accommodate more facilities and resources you've scavenged from your daily expeditions above ground.However, like This War of Mine, the game presents you with a ton of randomly selected scenarios, most of which will put you in a moral dilemma as you are forced to choose between forsaking your family's survival or your humanity/morality. As your bunker grows, you can also recruit more people to join you. Knowing who to trust enough to allow them access to your shelter is another dilemma that you'll probably need to face in this game.
Sheltered is the perfectly-designed game for players who find Fallout Shelter a bit too casual for their liking and This War of Mine a bit too restricted. If you' like what you've read so far, then do get the game from Steam. You can thank me later!
Starve.io
Starve.io is a unique IO game mainly because it is more of a base-building and survival game rather than just a hack-and-slash arena. In this game, you will need to collect resources and turn them into useful items which will marginally improve your chances of survival. The crafting aspect of the game is very much simplified but it can still take you a while to figure out crucial crafting details like how much resources you need to create a certain item. Also, a quick tip if you will - grab as much food and wood as you can at the get-go.As a survival game, there are several important "meters" that you will need to keep an eye on, such as temperature and hydration. Hunger also something that you will need to frequently deal with, aside from other potentially hostile players as well as other monsters like vampires and zombies if you happen to play its other game modes. There is even a "hunger games" version which frankly feels a lot like a battle royale game.
Unlike many other IO games where players are always pitted against one another, Starve.io is a game in which you can actually choose to coexist with other players rather than just swinging whatever weapon you have in hand at anyone you see... though, many players still do that pretty often, especially those better-equipped ones.
