DayZ vs Dead Island
DayZ
DayZ is a survival-themed, first person MMO game set in a post-apocalyptic world that's utterly devastated by a virulent disease. The game provides players with a beautiful yet dangerous map of Chernarus, a post soviet state to explore and to scavenge for whatever resources - as sparse as they may be - that you can find. Craft a wide variety of useful items or use the materials you have to improve or customize the equipment and weapons you already have... literally every item in this game can be upgraded. You can customize the look of your survivor with a wide variety of clothing too.Previously a mod for the game, Arma III, DayZ had come a long way to now being a standalone game. Unfortunately, the game is famous for its player-breaking bugs and glitches, and well, this is pretty understandable considering that the game's still in its early access phase. Due to this, even the most hardcore proponents of this game, the ones who has put in hundreds of hours into this game, will advise you to not get this game unless you truly want to help out with the game's development. If not, the game is more frustrating than it is fun, as exciting as the concept of the game may be, and we would not recommend you to get this game in its current state.
Dead Island
Dead Island is a first-person, zombie-themed action game that is set in an open world tropical island getaway called Banoi. With a compelling storyline to keep you hooked, the game's campaign features scavenging for parts as well as crafting and augmenting weapons (mostly melee) in addition to the whole smashing zombies' brains in gameplay. Not to mention, you can even play cooperatively up to four players.The character progression in this game is simply astounding as well, allowing you to develop your character based on your preferences.So, to sum up, if you love zombie-slaying/bashing and you don't think The Walking Dead has enough of it, then you'll enjoy playing Dead Island.
