I've played quite a bit after they fixed all the issues the first day. It's already 10x more fun than day z.
I play as just a lone wolf, and am friendly to everyone. Seems like people like to yell "friendly" then try and back stab me. That's the main reason I don't like having friends in these games. People always want your stuff.
I already got a 308 rifle, 1911 handgun, and about 30 rounds of 45 ammo, and 1 308 round, so it's not that hard to build up your inventory pretty quick by looting places which is nice. I only use the bow though to fight people because I hate wasting ammo. Also I noticed any time I bring out a gun, all the noobs start running at me with their fists since they got nothing to lose, and want your stuff.
Overall the game is very fun, and you can build a character up with loot within a few hours. Also hacking is punishable by a total ip ban on all of sonys games which is a bonus.
