Undying isn't so... gritty as the others. Has a more literary flair to it. Fucking awesome game, though, and an outstanding horror game in its own right. It isn't as rawly malicious, but has that kind of deep-seeded family rage thing going for it. I don't know if you ever played Clive Barker's other game, Jericho, but that one seems like it could be in line with some of these. I don't remember all the details, but it had that sense of twistedness and grit some of these others do, though it's certainly a more fantastical horror kind of thing. It's been too long for me to remember specifics. It got panned in reviews but I thought was a solid game and lots of fun. You can see a video I posted ages ago:

I enjoyed The Suffering pretty well, and both Condemned games. I believe at the time I played some of these I also played through both Shadow Man games, Dreamcast and PS2, if I recall correctly... and I don't remember enough about them to give much insight. The Darkness and its sequel are a touch less on the twisted side, but do feature some twisted moments, revenge-murder, and the first does a great job of escalation to the point where you really have to question what you're doing at a few key points. The new Splatterhouse is basically a gore-machine, but I seem to remember it going a bit deeper than that despite seeming pretty thin when you first start. It ended up surprising me any number of times.
I'll think on this some more. I feel like I should be coming up with more and better ideas.
