I want to play Ark: Survival Evolved with a friend. We both got a PS4, but no PS+ subscription (yet). I've read that you can host a non-dedicated server on one of the consoles or get a 3rd one and host a dedicated server there. But I'm unsure of how many PS+ subscription are required, if any at all. I've looked on the web, but found contradicting information from several years ago. Now I'm even more confused than before.
Do you need a PS+ subscription, when hosting and playing on a private server? If so, how many PS+ subscriptions do you need (e.g. 1 for the dedicated server + 1 for each player)?
