Before the release of Dying Light, there was a huge hype that Dying Light is going to be the best horror game of all time. The game published and it proved that people no more get afraid by the Zombies. A fun study was conducted by Polygon where they proved that people were more furious about the height of several situations in the game than the zombies. I personally agree to them.
Zombie itself is not a fearing topic anymore in the gaming world. All the statistics showed that games which were based on Zombies did poor in the market where Battlefield and Call of Duty type actions did awesome. Is it the end of an era? I think so.
Update: Dying Light launched for windows, Xbox One and PlayStation 4 last week and the sales are low till now. Let's see what happens next.
