As someone who loved Supreme Commander, I really wanted to like BAR, but I found it felt like death by a thousand cuts. I last played more than a year ago, so things might be different, but the QoL felt really lacking.
SupCom was my first RTS and I have fond memories of turtling on massive maps that would crash after hour 4.
Planetary Annihilation scratches the itch and reminds me that I am very bad at strategy games whenever I think I might be smart. It's probably the most fair game I've played that I am completely awful at.
There are so many qol things in bar that I would love to see in faf. Area mex build, for example. Sticky unit grouping, draw unit formation is essential. Reclaim/repair area. Unit and command queue jumping. That said there are a few faf ones I would like to see in bar too.
