Private Server/Lobbies

Overall, ability to host a private server (free or paid, Onward/Pavlov have a similar system) this opens the door for the Milsim community and can generate a huge player base.

I know this is probably the last thing to be thought of, as your team is continuing to polish the game. This would bring a lot of great gameplay, custom map creation (if able) and enhanced suggestions for realistic play-styles.
