OP, I too was late to this party about a week after Uncharted 4 came out and ever since, my ps4 has just been a Bloodborne machine. havent even touched Uncharted 4 since. this game is seriously amazing and I HATED demon souls which made me never try any of the Dark souls game.
The only negatives to this game for me are the shitty fucking Chalice dungeons. they are the absolute worst!!!!!
also Laurence the first Vicar can eat a bag of dicks for all I care. Most annoying and lamest boss fight in the entire game (outside of chalice dungeon bosses. which some of them are just really bs). His range and 360 attacks combined with the fact he barely gives you any openings to attack and he recovers from most of his moves farely quickly so he starts to move away as you get close is super annoying/feels cheap.
Oh and lastly... grabs in this game are OP/annoying as shit/kinda counter intuitive in regards to the game's concept of "being more aggressive" and makes it feel they are a game design flaw in that respect. but thats just my opinion.
You do Chalice dungeons for Uncanny/lost version of weapons, Gems, and bloodrocks. there is very little lore so dont put yourself thru the hell of chalice dungeons if you arent PVPing. seriously not worth it.
This is a great podcast that kinda goes in depth as to why the Chalice dungeons are pure shit, and discuss any lore implications from them, the very very little there is. (theres another part to this on that very same soundcloud page)
