I somehow only saw this reply now. It’s funny to meet other Arma players on here being that Lemmy generally seems to be a pretty progressive-leaning community and I don’t necessarily think the Arma community, on average, would be a super compatible demographic. Granted, there’s bound to be some crossover.
Anyway, judging from your comment history I get the vibe you might enjoy mods like overthrow and antistasi. If you’re not familiar, both are open-map game modes where you slowly build up a resistance movement to an oppressive government or occupying force. They’re literally the only way I personally play the game.
