Hey I was thinking about buying this game too play with my wife and I was wondering is there a way to just play 2 players and save out progress and be able to invite ppl to play with us but keep it private like a passworded game ?

if you own your own server you can probably host a server. idk how that all works. but you can get a like 4 slot server for like ten dollars a month and just put a pw on it.

yes you can host on your own server (it would require your computer to be on) just look that up
or you can use hamachi as a server hosting as well (i dont think it needs your ontime im not sure)
or buy a server from a hosting site, usually costs x dollars a month

and for these servers you can just send the ip only to the people you wish
assuming they dont tell anyone/post it online no one unwanted will join it cuz they wont find it

ya i got it figured out with an extra pc of my own, its a great time!
