Flappy Bird vs Starve.io
Flappy Bird
Flappy Bird is one of the most infamous hypercasual games out there. In this game, you need to help the flappy bird make its way through the sky that, for some reason, is covered in green pipes that resemble the ones in the iconic arcade-platformer, Mario.The game was designed to be insanely-easy to pick up - after all, you only need to tap or click to keep the bird afloat. However, playing the game can literally drive you insane with frustration because of how difficult it is. Needless to say, you'll see the "game over" screen a lot more than you'd like to within the couple of minutes you spent in the game... and that's a fact.
Flappy Bird, along with multiple of popular mobile games, helped paved the way for an entirely new genre of games to emerge. The game is definitely more than the hundreds of memes it gave rise to.
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.
