Bloodborne really suffers from a lack of content. There just aren't all that many weapons, items or covenants, which leads to a serious lack of build variety and experimentation, as well as it being somewhat lore deficient, since a significant portion of the background lore in Souls games comes from the item descriptions.
Chalice dungeons are really not that interesting, because there's only one unique weapon you can get from them, and the rest is pretty much just grinding through procedurally assembled prefab rooms for randomly statted bloodgems, and it takes far too long to get any of the interesting ones, leaving the bloodgem system kinda samey and boring unless you invest inordinate amounts of time into it. Otherwise, you just slot in the largest +ATK% gems you've got into your weapon of choice with no real thought whatsoever.
I honestly haven't touched the game since the first week and a half after I got it, and the half week was me struggling to justify to continue playing the game.
The aesthetic and core gameplay is fantastic, but it really does feel a little barebones in a lot of ways.
I turned on my PS4 for the first time since March yesterday, then just turned it off again. There's still nothing else to play on the damn thing, and I'm just going to keep whoring my PC with the Witcher 3, GTAV, KF2, a bunch of stuff in late May, and then more all throughout summer.
