So, I am still evaluating DayZ and the other versions of it that are available. Thus far, on an official regular server, I very much like the game play and difficulty of the maps, the spawns and the loot with the exception of creating a camp where it doesn't need to rely on tents and vehicles for storage.
I looked at Origins briefly and at first it seems to be very PVP in nature. The map is challenging and there is a fair share of hackers roaming the servers at the moment. I haven't had the opportunity to evaluate the base making and would like to put in more time and see if I can get past the heavy PVP and away from the hackers to give this version it's fair shake.
I have also looked at the Dayz+ mod and played shortly on an official server and immediately found that although the version was advertised as the DayZ everyone wants since it was generated on user feedback and the most notable features were the ability to build and the lack of using bushes to hide from zombies it seemed to have a lot more than that going on. I found that the zombie difficulty was way higher, with most taking 2-3 wacks with a hatchet. Loot spawns seemed no different than normal with more meds mixed in the industrial one I was on, but not once did I see building material. Then the damage/alert system is not right. I found zombies aggro with out my combat indicator flashing until they hit me and when they hit they hit hard. I would bleed easily, have a broken bone or the worst was the poisoning. Overall, not what I thought was advertised. I couldn't walk off of spawn and grab some loot without dying. Not a fan so far, but as with the original mod, it might take some getting used to.
I'd like to see what anyone else thinks and let me know if they find something they like as well.
