Dayz is fun and all but not alot of people have it and its limited on what you can do, as base building is a yikes and not really worth it. I would recommend Arma 3 Exile or Arma 3 Dayz, as it is way more developed than Dayz Standalone and 100% of the unit own arma meaning more people can get involed. Arma 3 Exile/dayz offers more for people to do as you can base building and have a faction/Group system that works, and easily change the loot and get more mods into the server.

Another point is that Dayz standalone is limited on what you can do within the server besides build a base that any one can get access too as the building system sucks, and just going to north west airfield to PVP. but when it comes to Arma 3 Exile/Dayz you can have AI missions, Mods, More players as its more open to the unit, and also its on arma so people will know how to play with the controls. as Dayz standalone is a yikes.
