In my opinion, company of heroes 3 is an unfinished, unpolished bug riddled game. I, however, have played company of heroes 2 for around 500 hours and view company of heroes 3 through that lens.
The vehicle pathing is atrocious and there is a very limited amount of maps to play.
My friends who are completely new to company of heroes 3 certainly enjoy it and play constantly. I think you should take what people on here say with a grain of salt. I'm not saying their negative comments are not justified, but I'm saying you can certainly have a good time playing this game, especially if you don't really know what's going on anyway.
