2. Mortal Kombat. Another obvious choice, every game has female fighters and gruesome fatalities. AFAIK, you can mod MK9 to slow time and change the camera angles. The only disappointment is that the every fatality is scripted and when you saw it once, you saw it all.
3. Bloodrayne 2. Must have for every one of us. The whole game is about sexy vampire in a latex suite who violently kills her enemies and drinks their blood. There is a lot of female enemies, dismembering, different finishing moves and stage-based fatalities such as working buzzsaws, fans or a spears to impale.
4. Fallout 3/New Vegas/4
As our friend Shadman said, the gore in this game is almost pornographic. Slow motion showing dismembering limbs, exploding heads, grenades sending bodies to fly, lots of female enemies, cannibalism and more. And this is the open world Bethesda game, so there is thousands of mods you can install, and this mods has almost everything you wished for. New Vegas also has very interesting story and quests. And you can play as the bad guy in all of this games.
6. Obvious Hitman series.
A sandbox levels with a limitless ways to kill anyone. Stealth, fibre wire, crowling and hiding bodies, gun blazing through the scared crowd or making the traps - this game makes you feel like a serial killer. Lots of females, spectacular animations, bullet holes, wound animations and so on. New Hitman series is probably the best, Blood Money is a classic, Contracts is the most gothic and edgy one, and the Silent Assasin is almost impossible to stealth through, but pretty fun to play through with occasional gun blazing. First Hitman is a buggy mess and I don't recommend it, though I had my fun in it.
The main fun in the game is to run over pedestrians on your car on a large sanbox levels with a different bonuses and weapons. First game in the series is sprite-based, but pretty fun though. Carmageddon 2 has great physics system, ragdolls and dismemberment (pedestrians may even live without some body parts). Carmageddon: Reincarnation and Carmageddon: Max Damage are the most recent and graphically advanced games, but pretty depending on your PC.
9. Unreal Tournament 99/2004/3
Fast arena shooter with female enemies, gore and variative gameplay. Its very satisfying to kill in this game, with the diverse weapon arsenal, gameplay modes and mutators. 99 has the "Nali weapons" and a "Butcher" mods to increase the goryness. UT 2004 has the "Ballistic Weapons" mod with the overhauled gore system and a new weapons.
10. Tomb Raider/Resident Evil series
People are saying the rebooted Tomb Raider series was made by guro lovers. There is a lot of gruesome ways Lara can die in this game. The same goes with the Resident Evil 6. You can watch examples on Youtube or play it yourself, maybe with the nude mod.
I didn't play the old TR/RE games much, but I'm sure there is some gory moments too.
Other notable examples:
This games: http://granony.r.ribbon.to/game/index.html
Torture Game 3
Manhunt 1-2/The Punisher - lots of gore with the male enemies
GTA, especially V with the dismemberment mod
Max Payne 3 with the female enemies mod - I don't know where to find it now though, there was a thread on Undertow website.
House of Velez 1-2/VHS slasher games from Puppet Combo
Happy Wheels/Guts and Glory - cheesy arcade racing games in which your character may be dismembered by countless user-made traps and obstacles
Garry's Mod/Source Filmmaker - You can see great EVMC's and Pestilence's works in /3dcg/ or play Garry's Mod - this is the universal sandbox to create eveything. There was a dismembering mod, which allows you to dismemeber any model with the fountain of blood and a ragdoll torture map. SFM is the very user-friendly and advanced tool to create the movie you want, but very dependning on your free time, PC specs and disk space.
Monolith's Blood - the name speaks for itself. Atmospheric and satanic gory shooter. Fresh Supply on Steam is the fastest method to run it on modern rigs. Painkiller: Black Edition is fine too.
Grezzo Duo - a shizophrenic and gory Doom 2 mod. You should see the gameplay on YouTube - it's worth it. The sequel is almost done.
Also, Brutal Doom
Darkest Dungeon with some erotic mods - if you want to play as the team of constantly hurt and suffering girls. New X-COMS are kinda similar in this way
Party Hard 1-2 - it's not a good game, but maybe you'll like it
Afro Samurai had some moments.
Just wanted to mention that myself but you did it first.
however they made a nice guro cartoonhttps://www.youtube.com/watch?v=33-S3wN1HXk
RDR2 has a pretty satisfying gore system.
But does it have sloots or strip clubs?
No stripclubs but there are plenty of prostitutes.
while eat blocks of monoglutamic acids
or a cheap knockoff of blue cheese mozarella
