Never heard of them. I guess this would be a prime example how an entire IP can be ruined for people because of the first impression from the first game.
The one I played was indeed at the era of COD 1 gaming (the only good COD game in my opinion). back then Brother in Arms was advertised as a realistic ww2 shooter and not sugarcoated COD game, but after trying it to me it seemed like it was sugarcoated with arcade just as much as COD, but they put so much sickening melodrama in the campaign, that I uninstalled it after 30 minutes of play.
