Well, the mods do some heavy lifting for sure (I mean, the game is literally unplayable without the unofficial patch), but they can only fix so much. The game was - much like Cyberpunk - shipped in an unfinished state that is to some extent beyond the scope of repair for mods. The final third of Bloodlines is not great. You can tell they ran out of time and had to cobble together an ending somehow with what they had. It devolves into a series of combat encounters in a game that is not exactly famous for its combat gameplay. Compare the last sections of the game to Santa Monica to see what I mean; imagine if they were afforded the time to give the whole game the same amount of thought and polish as they could Santa Monica.
Still, much like Cyberpunk, when it's operating at full capacity it really hits the spot. Driving through the rain at night in first person through Night City gives me sort of similar vibes as walking the rainy streets of Santa Monica, listening to Rik Schaffer's phenomenal soundtrack. Both games nail the atmosphere, at least at times.
They're actually fairly similar, carried by their characters, stories, setting and atmosphere rather than gameplay.
I also have to mention the combination of Bloodlines cartoony art direction and the facial animation rigging of Source Engine. The characters are incredibly expressive for a 2004(!) game, it really holds up well.
Did not expect to be thinking about reinstalling that today, but here we are!
