Not sure if this is a trolling comment by a jealous dev or fan of other games, or you are actually being serious. With only a few posts on your account I wonder.
Regardless, I'll bite. I think the dialog in BM is very, very good. And many parts are laugh out loud funny. You must have missed all the Hanna scenes.
As for the MC, not sure how he is self-absorbed, more than any other MC in a game. They are the main character after all, so the game has to somewhat focus on the MC's opinions and feelings about the situation he is in. There are a few parts that are a little abrupt, such as the initial few scenes with Katie, and also regarding Rachel pills and taking advantage of her intoxicated state, but I get that it her secret desire after all (plus porn logic), but its a minor point from my own perspective, and it didn't detract from the rest of the game, which is excellent. I would put it at the top 10, absolutely, and depending on my mood, perhaps in the top 5.
