I think that DayZ tells a story about one of the countries (and most interesting for me, for example, because I'm from Russia and I feel almost like at home on the map, lol) and in the future there will be more DayZ games (sequels or add-ons or side stories) in other countries, with other zombies and so on :)) But maybe not the whole Earth is infected, only Chernarus ;)) Only Rocket knows, lol. To be honest, I really like the setting of DayZ, because it's so different to any another game. All the game developers have a crush on USA, but it become a bit boring already :)) DayZ is really something original, complex... I think the atmosphere of post-soviet remote places / villages is far more scary than modern towns full of zombies, actually :) P.S. Excuse me for the poor English, hope you've got my "message" :) P.P.S. Here are some photos from Russia :)) Somewhere near the Vologda: Really looks like Chernarus, isn't it? :)) Sorry, I don't know how to put the pictures under the 'spoiler' tag on this forum.
