Arma (or Flashpoint before it). Although it’s gotten slightly better in that regard, I think. Haven’t run it in quite some time. It’s still probably the best there is for milsims though.
It has the potential to be an amazing game. But it probably never will be.
I fire it up once or twice per year. It looks great. Beyond that… it’s kind of fun to explore a bit, but that’s pretty much it. Not sure if anything will ever become of it.
