I'm not even sure why its age restricted. Nothing stood out to me as being over the top. Violence against monsters or something I guess? Maybe they algorithm'd Ian and thought he'd drop a few cocksuckers.
You can tweak a lot of the settings via ini. i had a server up but increased the rates of everything to a fun level since my friends and I only get ~ a week out of it before moving to new game(s).
A lot of games are like that which is one of hte upsides of VR. DCS not so much but god damn VR flying titles (DCS, MSFS, even VTOL VR) are so impressive.
Kind of weird method since you can go into your "saves" folder and edit the config file there and line 2 is "crossplay_enabled". I disabled crossplay right off the bat because that crap is almost always broke early on in games that have it.
