Yeah, Bloodbourne is not niche. If I didn't already own a PS4 I would buy it just for that game. It will sell systems without a doubt.
Total BS. History lesson kids. Dark souls 1 and 2 and Demon Souls did not sell well. It was successful for a niche game only. Stop with the delusions.
So, do you kids just talk out your asses all day, or what?
To be honest, Demon and Dark Souls are more of a gamer's game and spread by word of mouth. I greatly enjoyed the series, but it isn't accessible for everyone, and you probably won't it alongside COD and Pokemon on a Walmart display.
