I realize I'm feeding the troll here, but I did want to address the "immersion" question: No, I'm not saying BM should ignore "immersion", or in better terms, its "flavor". It wouldn't be the same game if it didn't incorporate the feudal elements it does.
What I'm debating is if one can truly be immersed in a lightweight game like BM and its dedication to "you get out what you put in". I guess some people get very invested in their characters, sure, but that's not really caused by the game mechanics. Besides, the term is used in all kinds of games, including those that are much more outlandish than this. It's less about what things are called and more about how much it makes you care about your character's actions and empathize with them as they experience the corresponding consequences.
