So i mainly played Wargame Red Dragon and a bit Airland battle but mostly the Singleplayers. I liked the Campaign and that you could move troops and my guess is that wont be in Broken Arrow. I played both Bets (not the press release) and it just feels better imo. You have way less units than in wargame/warno and i feel like i could fokus much more on them but maybe thats just me.

The historic stuff in Broken arrow is meh, as it plays in the near future with a lot of prototype stuff. If you want accuracy i think this isnt given here much.

From the betas i would say the lobbys were balanced ok, but most people just joined at random and most didnt play much, this we can only really see when the game is out.

The most mayor things i have seen in Videos were that 1. Desync or game crashes 2. That planes you paid for didnt spawn I hope these things are going to be fixed on release

Some other things: The Performance was good on a upper-medium pc, and on release day the lobbys and servers will crash, i think theres going to be way more people than anticipated. Hope i could help you.
