Okay, so now I've completed the game.
I must say... Not a big fan of the ending. Both the twist and also the resolution of the cases were not my thing (The latter being a stretch of the usage of "Resolution"). I'll say no more to prevent spoilers.
The post-ending scene is very W3-esk in that it directly points to a certain handful of decisions that impacted the actual story (Of which there are literally 2 unless there are some hidden endings I don't care to try and find). There's probably some dialogue changes based on some dialogue options that affect temperments, but besides that... 2 actual choices, one of which is nullified anyway if you pick the "Wrong" choice for the first one.
Gameplay fell off considerably after the first portion of the game. Way too many "Stick you in an arena with constantly spawning dudes" sections that completely nullify like 80% of all the skills in the game that are focused around stealth. Meaning the game revolved heavily around the shallow punching gameplay or (As in my case) abusing the (Only) 3 powers that enable takedowns in combat. Like, bruh, there were hardly any powers to begin with and the game then forced most of them to be literally useless.
To say nothing of the tedium that was actually traversing the game. With no fast travel and no good options for mobility (You have your Vampire Sprint but that can't be used on the ground because it fills up your masquerade break in seconds. You can use it on rooftops but there's too many tall buildings that get in the way to make it actually viable as a means of travel to not mention the parts of the game when rooftops are FULL of enemies that'll be shooting you) but a LOT of "Run across the entire city" moments.
Sidequests were trash. Outside the 3 that were literally "Go find all the collectables". There was just a copy/paste of 3 remaining ones "Go do a fetch quest", "Go kill a specific civilian" and "Go kill a specific enemy". Their kill ones at least had the decency to offer a non-lethal solution.
Bloodlines are so shallow as to be irrelevant. Despite them being a literal part of the series title. Your choice of bloodline only changes a few dialogues (But not in a meaningful way. It'll just be referenced like 3 times throughout the entire game), your punch animation and your base passive (As well as cost to acquire certain skills).
Overall, the game is "Passable" in that it wasn't horrible to play through, outside some bugs (Like clipping into a wall after jumping, clipping into the floor when crouch sprinting, enemies not having the takedown options show up for no reason for an absurd amount of time after spawning in and the skill for "Mortals can't hurt you when you're feeding" basically only working like 30% of the time)
But I wouldn't consider it to be particularly good. I don't see myself doing another playthrough of the game ever.
Maybe I'll still pick it up some day, on a deep discount, if somebody manages to mod out most of the clown-in-your-head stuff.
That's unlikely to happen.
Since sadly, Fabien is much more integrated into the game than Johnny.
Like, whereas Johnny is basically irrelevant outside a few missions like Tapeworm. Fabien and the Nomad are almost constantly talking back and forth throughout most of the game. With a couple of the "Memory flashbacks" being directly relevant to interactions as the Nomad.
