I won't be adding time duration estimation for the Arma 2 sections of the list including its mod unless requested since it would take quite a while. I'll do it if any communities or individuals out there wants to use the list to help them out find what mission to play.
Overall, I'll be focusing on the Arma 3 section, but mainly on small player count missions (2-6 players) since I actively play Arma 3 and it would be easiest for me to sort out small player count missions since I can find someone to play with and it'll benefit those who wants to play during off session for coop nights. I may throw in a larger player count mission here and there if I find the needs, feel like it, or are running out of missions to play with on the server and find the needs for some sort of nostalgia night. Although I'll actively maintain the Arma 3 list, it'll grow at a slower rate since I'll be adding missions at higher scrutiny for this one.
