DayZ is, one could say, a unique game in its genre – here you have survival, shootouts, and just a big world to explore. Also worth noting is the good online player count.

In Dayz ILLEGALS you can become friends with someone, and someone else will become your enemy.

You take a screenshot of landscapes at sunset every time, and ask your friends to take a photo of you.

You just run to loot and die, but you want more and you can't quit DayZ. You die and die, there's no way around it in DayZ. Either you get killed, or you die of hunger.

Still, the game is really good, so I veeeery highly recommend playing it.
