As of 2023, I still stand by that for more than a decade now, Arma 3 is still the best mil-sim sandbox. Reforger has been disappointing borked like hell so far, and arma 4 is still a road too long.

As an Operation FlashPoint to Arma series "veteran", I cannot commend how far has Bohemia Interactive has come since the early days. Arma 3 as of writing is still one of the most definitive of Mil-Sim games that you can access. Arma 3 provides much catering to Long time fans and newcomers who have never truly experienced a variable scale of combat, from Infantry ground level to Strategic Command of entire units and battalions. This is one of the few games I actively play at all, and usually don't bother with any other Shooter titles.
