Everyone who's played this has paid for it, FYI. It's not F2P yet.
Positive, over all.
Some of my gripes are that the map is so small for the player limit that it crams far too many people into 8KM. There are a lot of people complaining about loot, but loot is EVERYWHERE after server restart, which means that loot is over saturated but there are so many people crammed into 8KM that a billion people are getting a small piece of the pie as soon as possible, making it look like there's no loot remaining.
Once the map size is increased (which will is planned to be done at least once prior to release and then done repeatedly post-release), it'll be a lot easier to find loot. Too many people griping about loot when the root of the problem is player density.
Base building needs work. Some locked doors can be opened by anyone. Bases need to be "repaired" with a hammer as they decay over time. However, it's like 1 or 2 days and your entire base is gone. This should be pushed back to 5 days so it doesn't require players logging in every single day to repair their entire base. Not that it matters anyway, since you can just walk in in many situations.
It's a DX game, so cheats are instantly available as always. Sigh.
Teaming isn't in the game yet, so no clans or groups or parties or friends list or something yet.
Gameplay is fun, PVP is REALLY fun. The discovery system is novel. Playing on a pvp server with recipe wipe, headshots only, and 1st person only is hardcore mode. It's great.
Sony has been RIGHT on the ball with bug fixes and updates and things. They're doing an impressive job paying attention to their game, which not many other companies usually do. Follow John Smedley and H1Z1 on twitter/reddit for update news. There's a Dev Tracker somewhere too but I don't have the link handy.
