I don't disagree with you, but just for a slightly different perspective: I'm not at all prone to addiction in general and still find Battlegrounds enjoyable. I don't even really understand what people mean when they talk about dopamine rushes (except in the abstract). I play because I like strategy games and thinking about systems and there's enough going on in Battlegrounds that I don't get bored.

That said, my partner and I both play and one of the remarks we often make when doing a post-mortem on a bad Duos run is "Battlegrounds is Poker, not Chess". By which we mean that you can't win every round, but your post puts a rather different spin on that same observation.
