I used to play the original TA a lot and BAR is very well done. Much harder than the original though - I had no trouble with TA campaigns but I have not even made it halfway with BAR before hitting skill wall. Not a teen anymore so it’s hard to motivate myself to try and push through. :)
There's also Zero-K on steam and it has an actual campaign. Last time I checked BAR had none, but it was on the roadmap
You’re right - it’s not a campaign as such - it’s a set of scenarios (currently 22) in increasing difficulty. I haven’t played for a while after getting stuck but checking now I got stuck on the 5th scenario - even worse than I thought. :)
I played Zero-K several years ago and it didn’t stick in my mind as much but maybe worth revisiting it - thanks!
Reading about it seems to suggest that it’s even deeper in terms of strategy and tactics so I will probably struggle even more. :(
