Great game. Many players still play it, including myself. A lot of amateur add-ons have been created for ArmA 2, so it’s very easy to find something new for the game.
The game has an excellent mission editor that will not let you get bored. You can create a lot of different maps, and then go through them alone or with friends.
Multiplayer is teeming with a variety of servers: you can find any server to suit your taste.
But there are a lot of glitches in the game. Over time they were corrected, but at the start everything was very bad... The plot is also not particularly interesting, everything is done too banal.
