I'll revise my review just slightly.

Project Zomboid, this is the type of game you can make friendships with, and lose them.

I will start with the realism. The realism in this game is quite high, and it makes for a enjoyable experience if you're like me, and you enjoy realistic games instead of arcade-like games. This game is also very hard, not Dark Souls hard, but still hard. Your settings are extremely up to you and you can do whatever you want with this game. This game, also, has infinite potential. The amount of things you could think to add to an already extremely realistic isometric 2D zombie game is crazy. Despite how simple the graphics may look, it certainly is something you should look past towards the quality and dynamics of the game. They have made, in my opinion, a game that is better than most AAA games on the market, with a small team, and a supposedly short budget. This game is better than the Forest, in survival aspects, and the combat, well, it's simple, and simple is good, especially for how everything else goes in this game. Just about everything about this game is very intriguing and takes a lot of time to really get to know. I already have 500 hours + in this game, and I've made many memories with my friends, and just myself, on this amazing game.

10/10, would play.
