Zomboid was originally inspired by CDDA. Much of the game flow and ideas are 1 to 1 copies. The biggest difference is that CDDA is a turn based game that is played on tiles (think rogue or nethack). From the inventory system to crafting to base construction to reading books, it’s all there.

Oh. Except bites aren’t instant death. There’s no zombie virus. Dead bodies rise up (including yours!). You can still get infections and die from them, but you can also just clean your wounds. 1v1-ing a zombie is suicide though unless you have a decent weapon.
