Due to the steep start-up cost, there aren't a lot of PS4 Player Dedicated Servers quite yet, though they're slowly cropping up. Additionally, anyone who wants to easily find and play on your server must add you on PSN. There's just one catch and it's expensive: you must host the server on a second PS4 console. With so many customization options available, who wouldn't want their own unofficial, private, Player Dedicated Server? You may not be able to make Cross Ark Clusters with them, but you can adjust everything from taming speeds to the rate of experience, the materials gathered from harvesting, and how quickly the day goes by. PS4 Player Dedicated Servers are far more customizable experiences than Studio Wildcard's Official Servers.
ARK: Survival Evolved PS4 Player Dedicated Servers
That is no way to play ARK. So to get the full experience, at this time, there's only two real options: Official Servers and Player Dedicated Servers. Oh and good luck connecting at all if you don't have a solid internet connection. All guests are tethered to the host on a 200m leash, and if guests find themselves outside of this radius for whatever reason, they are teleported back to the host, foregoing any tamed creatures that may have been accompanying them. There is Host & Play, which is a neat way to play with your friends - on paper - but is in no way an enjoyable experience.
