I believe Improving the inventory should be one of your priorities. I would probably have double the hours in DayZ Xbox version if the inventory wasn't so laggy, makes the game experience very frustrating. I'd like to see you implement a quicker way to move items in and out of tents/cars/barrels etc its very time consuming and with the lag it's almost impossible sometimes.
Overall I am enjoying the game, it has so much potential. Just a few more improvements and tweaks and I'll probably have to say goodbye to my social life.
Keep up the good work!
