It starts off with your trying to solve the murder of the person who's body you've randomly entered from the future because it's a 4th wall breaking game where you ARE actually the Nomad Soul and the game talks to you, the player, directly. Fine, that's actually a cool idea, solving your own murder and only a handful of people even know you're meant to be dead. I'd be super down for that. Then it turns out demons are involved and there's this underground race of people and a resistance and a religion and you have to go find an ancient wizard to find an ancient warrior also David Bowie is an ancient AI god and I'm pretty sure I'm forgetting like 5 different factions because I'm having an aneurysm remembering that game.
I'll let the idea of the gameplay being a mix of dialogue based exploration, first person shooter, and 2D fighting game slide on handling because it was trying to do a thing, sure. It's old, whatever. But the it handles like ass because it couldn't settle on one thing and make it work.
Also the primary gimmick was that you could swap bodies by inhabiting someone new. All you had to do was die and hope someone finds your body to enter them. Eventually you learn to just jump as you like, kicking their soul out and leaving your old body an empty husk, decaying in the street. This leads to awkward times where in order to open a gate, instead of just asking the peaceful guy who actually probably would happily let you through, you have to enter his body (destroying the body you left and effectively killing this person) to flip a switch, only to leave again and need another body later. This is a mandatory event and paints you as a psychopath. That's not even getting into the stuff where you can sleep with someone's wife because you're in his body and she brushes off "What if I told you I'm a guy from another dimension?" as hot, dirty talk.
