I can happily say that after so many years of playing this game, I am STILL playing it.
Some people might consider it sad but I still stand by the belief that this game is one of the best zombie survival sandbox games this industry has ever had.
Sure, it has it's problems, it has moments when I ragequit because it crashed after finding a good survivor or death in ridiculous circumstances or just the most annoying AI behaviour, but those moments are so rare compared to how many hours I've put into this game and how more often than not, the game is truly playable.
So yeah, who is still playing it?
And if not, what other zombie games do you play? Or just say what other zombie games you play as well as this, I don't care.

I'm still playing it and I'm half way through my 3rd series of it on YouTube, very happy how it's coming along so far.
