Current player limit is the default 4, but I may increase it if we actually get that many players joining at the same time.
Edit: Someone asked about a chat, so I created a steam group for the server, you should be able to join that here: https://steamcommunity.com/chat/invite/EblxtBh7
Sounds like a lot of fun! I hope you all have a blast playing, and yeah maybe we'll pop in just to see how it's going. I promise no griefing :)
If you haven't hosted dedicated, we did find that Satisfactory is both heavy vertically and horizontally, most important is a high frequency clock. In the later updates they've done a great job sharding out processing to multiple cores, but later game it will still be very tightly bound by your best core.
Have a great time playing, whether this if your first or 10th factory, enjoy!
