Well in State Of Decay they sure can......I don't know much about game development, but isn't SoD a smaller, and much more simple game than dayZ?I mean its creators probably spent much less time and effort with the game, and still managed to implement that feature successfully, even along with relatively intelligent zombie AIs, which often use the advantages of it...... However, I got bored of SoD, it is too smiple for me, too few items, too more important quests, (even in Breakdown DLC), so too few truly FREE AND OPEN gameplay possibilities, always the same only one map, which I already know by heart, without any new, unexpected events, innovations or features.....and the most important, only AIs with very limited intelligence and very predictable reactions, no chance to play with or against REAL PEOPLE, which is actually the true challenge in this game genre. Well yes, I guess I will have to delay buying DayZ for now, until at least windows will become breakable and passable, IF (as you indicated) that will ever happen at all...... Thanks for the info though, you saved me 28 euros and a disappointment! Don't get me wrong, the game (according the gameplay videos) looks real nice, cool, and attractive, and all my respects to its developers for their achievements in it so far, graphics, sound effects, ambience, diversity, etc, but with such a serious omission, (at least for my taste), as unbreakable and even non-passable windows, I am not willing to start playing it. The game realism is just too important for me to try it out.yet. Thanks again for the info! Caccio out!
