I enjoy playing it casually every now and then. It's not a game that I, or a lot of people, could really get into like they do for dayz. There are things you may like a lot and things you wont. I found a good private server that I can hop on whenever I feel like to just go kill zombies and whatever, free from hackers/annoying KoSers who just camp loot spots to boost their killcount. It's a pretty cheaply made game, but I find it quite fun as a game to just play when I feel like hacking away at some zombies.
Was it worth the $50 I preordered it for? Eh, maybe not $50 but definitely would have been more worth it if I had only paid $15/$30.
