Black Survival vs Starve.io
Black Survival
Black Survival is a battle royale/survival game that will bring to mind games like PUBG and movies like the Hunger Games. However, as opposed to having plenty of players in a single game, Black Survival only houses up to 10 players on a deserted island. The island itself is segmented into 22 areas, each of which will gradually become "restricted areas" that drastically drain your health if you insist on staying in that area. It's also great that the game has a crafting aspect, allowing you to create hundreds of different weapons, tools and food items.Best yet, the game has an amazing myriad of characters for you to play as, each of them have their own backstories for you to discover. Characters are not all free, though you can literally play all of them by patiently waiting for the game's free character rotation. And of course, it also happens to be an anime-themed game... how many anime-themed battle royale games have you seen so far? (The answer is none except this one, by the way)
So, to sum up, Black Survival may have come out at just the right moment when the Battle Royale hype is at its peak thanks to popular games like PUBG and Fortnite Battle Royale, but it managed to innovate the genre and provide players with a fresh new perspective to the genre. You can even play this game for free while you're on the go!
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.
