Awful in so many ways but somehow irresistible to play accurately describes this game. For all its inherent shittiness, there's something it manages to do right when you're out looting and trying not to get chomped on. It really does emulate that "Walking Dead" feel. (I barely watched the show but I know enough about zombies to know this does a good job of it.) If it looked somewhat less shitty, and the overall design felt more realistic and less like the voxel game it ultimately is, I'd recommend it to a hell of a lot more people. There's something about the amount of open space in the game, especially in cities, that never fails to remind me its a voxel-based game, and a rough one at that.
I was also describing to someone last night while playing how the game just DEVOURS your time. It's really a game about time management. Maybe less so with 7 Day hordes disabled, but even then, keeping your forges running, scavenging food, looting, crafting, upgrading, base building.....there is almost no second of time in game that "should" be wasted, there's always something you could or should be doing. I'll be like "I'm going to get up and go smoke" or "I'm going to go change my laundry" or "I'm going to eat...." and then an hour later realize I haven't gone anywhere or done anything because 14 little things came up. It's almost like having a second job.
Generally the sign of a good (if deeply flawed) game when it sucks you in like that time after time. I sorta remember Terraria having the same effect in my first 40 or so hours.
