I love the game, I'm in NG+ but mainly working on chalice dungeons right now. I disagree that bosses are too hard for 1 person, only a few of them seemed that way to me -- mainly Rom the Vacuous Spider, Martyr Logarius and Ebreitas. I played a tiny bit of Demon Souls, a tiny bit of Dark Souls, and almost to the end of Dark Souls 2... I'd still call myself casual in terms of the Souls series. Bloodborne is harder but only until you get used to how the action works, or as Souls players put it, git gud.
Same could be said of Dark Souls, oh this game is easy! Because I am now aware of how the parry/dodging works and can take advantage of that.
I have a friend who sold Bloodborne to someone for $30 after getting past the first boss. Another friend who has been playing a few days and hasn't even gotten to the Cleric Beast yet. It's not even that huge of a learning curve, that doesn't mean the game is easy or really hard, it's just different from other games.
People complain about the areas being a maze but I found them to be really linear, and there's at least 2 shortcuts you can open in each area. The most maze-like area is the Forbidden Woods which is a huge pain in the butt, I don't like going there, mostly because I'm not a huge fan of every enemy being either a pile of snakes, a giant pile of snakes, or a man who goes crazy and has snakes shoot out of his head.
Being sucked in this game is the worst especially if it's a Brainsucker. They take 2 insight and do considerable damage when they latch on. Also the Brain Trust are nasty and look like the aliens from Mars Attacks. I like Mother Brain a lot though.
If it seems ridiculously easy with 2 people then you can probably do it alone.
Least favorite location is Nightmare Frontier because of all the poison water everywhere.
Already want the Bloodborne DLC! Need more!
Surprised nobody made a thread too seemed like last time I heard people talk about the game here they were still calling it Project Beast
