Most recently XCOM and before than FTL. Only generally happens with games that don't allow saving. Also usually not in a hard bit, but somewhere that I am just going through the motions without thinking much and get caught off gaurd due to laziness and end up with massive losses.

Honestly, The Witcher 2 fighting the boss in the old elven baths had me shouting at the monitor. I had to use some cloth to wipe all the saliva off the screen after I'd calmed down. Hopefully the Full Combat Rebalance 2 addresses my rage :D

JA: Deadly Games, mission 18, yesterday [it's 5:25AM], 4 or 5 times.
Minecraft Better Than Wolves TC, almost every time i die. most recently, yesterday.

Unstoppable Gorg a couple of months ago, I think. The whole game just wasn't for me, and I don't know if the game was just too hard or if I suck at tower defense, but I had huge trouble getting past every level and finally, around level 10 or so, I just thought to myself "no way am I ever going to be able to finish this" after a few failures in that level and did a quick uninstall.

More of a frustrated-quit. Some mission in Blitzkrieg II, where I finally cracked the big puzzle of the map and was then informed that I had to prevent a particular unit from escaping the scenario map. The text made it sound like this unit and several others would be trying to breakthrough my position so I set up defenses. A few minutes later, I get the message that I lost because the unit escaped. WTF - I didn't encounter a single enemy in that time, let alone the specific one I was intended to stop.

I really REALLY hate these types of winning conditions that get sprung on you mid-stream, and they're even worse when failure prevents you from advancing. So you mean to tell me that the entire war is lost because this one unit escaped the map? In this game especially, where the AI hammers you for charging in without a plan, it then expects you to charge in without a plan under a time limit.

I might go back once I'm done with SPAZ, and might not.

Truthfully sudden ragequit, Streetfighter 4 online play. Hitting a certain rating then going up against nothing but Sagat and Guile turtles.

I love fighting games but playing them online makes my anger rise exponentially whenever someone's being cheap. If I'm playing with someone sitting next to me or using the arcade machine I can call them out on their bullshit or throw a cushion at them or something, but online there's nothing.

Don't Starve has gotten my blood boiling quite a few times and some of those times were because of a glitch so that was really frustrating. I had to stop playing it before I went to sleep or it would keep me up half the night.

August 2, 1876. Wild Bill Hickok got his blood all over my cards. I was so mad. Plus I had aces and nine's! :(
Still bugs me! :P
Truth is, I don't remember. I don't usually quit from anger, just general disgust. Maybe it was Mount & Blade Warband when I got TK'd 3 times in a row. Still, I don't know if I rageguit, I generally find it funny when bad things happen with such frequency. Games help me get over bad things that happen in my life, they don't usually stir up bad emotion with me.

hmmmm

War of the Roses I think was the most recent. Another relatively recent one was Giana Sisters. Got to the last boss and just couldn't beat it, i'll give it another shot later.

Platformers usually make me rage quit.

Prince of Persia: Forgotten Sands
Near the end, the water freeze button would not freeze the water. After ten times, i was furious and just quit. I got the game as a gift and i was still mad as hell. I will never buy a Prince of Persia game after that experience.

Mostly it's a case of be getting bored, irritated, or fed up with a game that I've lost interest. In that I measure the effort I'm putting in for progress vs. the reward I feel and if it's never balanced that's it. Tomb Raider 3 was a recent example. But I do have a game to fit your criteria.

Virtual Tennis 3 via way of the A.I. committing gross acts against physics that should be banned by the Geneva Convention. Every perfect Andy Roddick-esque would-be-an-ace serve you bomb down the line returned as if it was a powderpuff ball at the local tennis club. Every single desperate dive to one of your rocket groundstrokes returns the ball perfectly in play. You have your opponent on the ropes deep behind the baseline, but every swinging, scrambling, low-percentage shot turns into a perfect passing shot that not even Rafael Nadal could do. Aggressive lobs that might as well be fireworks shot over your head with no chance of hitting (whereas yours are pitilessly smashed). Change-ups in pace that are simply impossible. Drop-shots created out of thin-air that would make Martina Hingis weep. And the fact that the A.I. never nets a ball, and unforced errors are once in a blue moon.

Yeah, I've rage-quit that game.

Didn't stop me from re-installing it a few months later. Another Grand Slam, and another damn tennis itch to scratch.

I don't recall ever ragequitting a game but I know i have certainly taken rage breaks and nearly rage broken stuff too.

I'll sometimes get irritated with a game and quit, permanently or not. As far as full-on ragequitting, never that I recall.

I have been disappointed by quite a few (many ) games. Frustraded too. Even bored to death. Sometimes to the point of unistalling them and getting rid of the game. I have been spending les time on games in the last couple of years. So I tend to avoid situations where I'd repeat again and again the frustration. The last game that really infuriated me was sword of the stars II, after the enhanced edition and the successive improvements still failed to make something remotely fun out of it.

How about the last 5? I'm not a patient person.

Two Worlds II: OK, I can deal with being forced to play a dude in 2013 (I'm picky on this, would rather the choice at least be there for an open world game where story pretty much doesn't exist). What I can't deal with it a control scheme that feels terrible on M+K AND controller. No matter how I try to play this game it feels clunky as hell and makes combat an absolute chore. Oh and I wish they would have just went with text bubbles, the voice acting is that bad. I can't deal with that shit, I would rather boot up the mediocre Risen, at least the voice acting in that isn't completely grating and the combat is passable.

Capsized: I liked the game at first until I tried using the hook the hook to move around. It was so wonky that I couldn't deal with the terrible controls and quit. Doubt I will ever go back.

Hotline Miami: How do people find this pile of crap fun? Its pretty much everything I hate in a game: trial and error, needing godly reflexes, getting killed from off-screen, and the perspective makes me sick. I'm just gonna do myself a favor and go with my gut next time for these masochistic getting punched in the nut simulators.

Disciples 3 Reincarnation: The game was awesome until I entered a battle and discovered the RNG. LETS MAKE EVERY ONE OF MY UNITS HAVE A 40% CHANCE TO HIT WHILE THE ENEMIES HAVE A 90% CHANCE. That shit pisses me right off and I couldn't uninstall it quick enough, which is a disappointment since I loved 2 so much.

Giana Sisters: I bought the game because someone on this forum was singing the praises for this game. I went into the game expecting something sort of similar to Trine, what I get is an old school platformer through and through. That one last an hour. I hate these things and I wish Meat Boy never came out, it spawned a movement that makes it almost impossible for me to pick up a platformer anymore without spending a bunch of time googling and watching lets plays to see if the damn thing is not a victim of old school design. /Rant
