Redneck Rampage is probably the most famous/well known of those, though I hardly ever see it mentioned when people talk about old fps games, etc. (though it has a gog release which is nice).
I played RR back in the day, and it was fun enough. Not as good as Duke or Blood, but a solid game nonetheless.
Powerslave. FPS set in Egypt, loved it but I have never heard another person talk about it ever.
I actually picked up the PS1 version last year, but I have yet to play it! I did play the PC version back in the day, but it's a completely different game than the PS1/Saturn game.
ecstatica
completely bizarre 3d horror/adventure game, featuring puzzle solving & some combat. you can choose to play as male or female. includes werewolves, dead priests, & scenes of torture & debauchery (both featuring nudity). hell, you can even choose the 'bad' ending, where, instead of rescuing the princess, you opt for luxuriating at an endless orgy! &, no, i'm not kidding:
they just don't make'm like this anymore :) ...
I think I played a demo of it 20+ years ago. Wonky controls, but an interesting setting and concept.
I love both games. I know its not cool to like Bloodrayne 2 at all, but it was one of my favorite character action games of the PS2 era. It would be interesting to see someone do something new with the IP.
I didn't like BR2 as much as the first, but it was solid. And yeah, I hope someone revives the IP.
A lot of DOS games I rarely see mentioned much:
Jazz Jackrabbit
Commander Keen
Halloween Harry
Cosmo's Cosmic Adventure
The 2D Duke Nukems
Monster Bash (one of my favorites)
I played most of those games too, haha. Jazz was a solid, if middling, Sonic clone, and Halloween Harry was a darn fine 2D platformer/shooter. Was Monster Bash the one where you walked around a haunted house?
I love these two games so much, I never see people talk about them.
Never played Time Busters, but Lost in Time is a great platformer.
Blood and Redneck Rampage. Not enough people discuss them just Duke Nukem 3D
Blood is one of the finest FPS games ever made. I love it.
Undying is a classic. Lovecraft meets haunted house horror. Too bad that planned sequel never happened. And I'd buy a remake of this day 1.
I came here to post "Cold Fear", but someone has beat me to it!
I have Rapid Racer lying around, and played Overboard back in the day. Both decent enough, but rather challenging.
I loved a game on pc (talking about 386) called...ports of call? It was a shipping sim with a hard af decking scene where you could wreck your boat and ruin yourself in about 6 seconds.
I played that briefly back in the day, but I think it was very popular on PC and possibly various home computers?
Heretic and Blood are classics, and Nosferatu was surprisingly good!
All objectively awful games I enjoyed in some capacity:
Krazy Ivan (PS1 ) : Cashing in on the Mech Craze.
Oh Jesus. Krazy Ivan was indeed Krazy Bad. I played it as a teen, and the game stank to high heavens.
I don't think anyone else but myself have mentioned it here.
It was the very first FPS game I ever played and it had a fantastic soundtrack.
I had that on PS1, and it was a great game. I should buy it again sometime..
Oh, and my pick for games I never see anyone talk about..
Sure, it's not the best thing ever, but I had fun with it. It was my first taste of the RPG genre too. Still have my copy of the game.
