Dead Island vs Starve.io
Dead Island
Dead Island is a first-person, zombie-themed action game that is set in an open world tropical island getaway called Banoi. With a compelling storyline to keep you hooked, the game's campaign features scavenging for parts as well as crafting and augmenting weapons (mostly melee) in addition to the whole smashing zombies' brains in gameplay. Not to mention, you can even play cooperatively up to four players.The character progression in this game is simply astounding as well, allowing you to develop your character based on your preferences.So, to sum up, if you love zombie-slaying/bashing and you don't think The Walking Dead has enough of it, then you'll enjoy playing Dead Island.
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.
