Not being a big gamer, I can'comment with much authority. I've played a bunch of Modern Warfare(s) and Battlefields, and Squad. But they all feel pointless to me when ARMA 3 exists.
It's _so_ janky but in my mind way more immersive for reasons I just can't fully explain, though they are something to do with the fact that good comms is the key to fun and success. It's also got a pretty major learning curve...
The community makes the game. The actual game is much less important.
The learning curve just acts as a filter that results in more like-minded people sticking with it.
I agree. I've played Arma 3 for more than a whole decade now. Most of it comes down to the open large scale combined arms experience not being available in any other recent video game from a first/third person perspective. There's now Arma Reforger, but it understandably lacks content.
