I recently saw Project Zomboid. Had heard about it long ago, and just kind of brushed it off as typical zombie game trash. Boy how wrong. Haven't played it, but looking at Let's Plays, it looks like as close to a video game adaptation of Max Brooks' Zombie Survival Guide as there will ever be. Brutal, bleak, realistic. The way the sound draws zombies in, the sheer numbers of them streaming in from everywhere, it nails that specific brand of fear.
I kind of like that there's no human enemies. Humans are part of the zombie fantasy, but I'm so sick of zombie fiction (any media) using it as a backdrop for more stories about dudes shooting each other, muh humans are the real enemies, especially when they make a human faction cannibals. I don't even find it realistic at all, peoples instinct is to rally together in response to disasters. I like that it's got a depressing last-man-on-Earth feeling.
