ArmA 3 is one of the best military simulation games on the market. The developers have fixed many glitches that were in ArmA 2. The graphics have been significantly improved, vehicle controls have been significantly improved, and the animations have become more human-like. Actions in the plot develop more logically than it was in ArmA 2; much more time was devoted to the plot.
The main trump card of the game is not the graphics or the plot. The main trump card is the mission editor and multiplayer. If you go into a network game, you can find a huge number of servers for every taste. The editor allows you to create your own maps, which can be shared on the Steam Workshop. You can also install fan-made add-ons, then the game will become even richer. You can do absolutely anything in the editor: from small battles to huge battles.
I give the game a high rating - 9.7 points. I take away the remaining 0.3 for some offensive glitches that are in the game. ArmA 3 offers such a wide range of actions that it is simply impossible to foresee all possible scenarios. This is where all the lags, glitches and freezes come from. But this happens rarely, which is undoubtedly encouraging.
