First one that pops into mind is Left 4 Dead 2. I'm not multiplayer guy so I was just going through the maps by myself with bots. The endings are always hard but the last one in L4D2, with the bridge, was driving me insaaaaaane. I have a weird pride thing that stops me from lowering a game to easy mode, so after 10 tries or whatever I just quit.

Oh I also ragequit Full Throttle, the adventure game, because it's puzzles were obtuse and stupid and I hated them. Story wasn't worth it. I should load it up and play through it with a FAQ someday though, just to experience it.

The closest to ragequitting I've got was probably with Assassin's Creed. I didn't like it, but kept playing far longer than I wanted to because the game is so popular and I wanted to know why. After hours of confusion about the matter, I got seriously annoyed that people like the game and felt like the game had slighted my honor somehow so I quit. The emotions were of such magnitude that some of the bitterness still lingers.

hands down god of war and any bloody way too many unnecessary quick time games including indigo prophecy

Quite recently. Many times. Trine.

I think it's self-explanatory, isn't it? But I've managed to finish the game nevertheless.

I ragequit football manager 08 yesterday (actual it was to day) at 00.08 I keept loosing to Arsenal.

When it comes to online games, where I play with other peoples (League og Legends) I never ragequit.

Yes, this game can be frustrating as hell. I still enjoyed it a lot a finished it but I agree it's absolutely unfair. The basic problem is that the game doesn't allow you to be creative. There is a perfect tactics in every mission. For example: take your starting troops and destroy one of the enemies immediately. Return to your base, create bigger army and attack the second. If you use it you'll win easily. If you don't - you will get annihilated. It turns out that the first village is not well protected but starts with enormous amount of weapons. If you let them develop they will crash you so you have to destroy them at the very beginning. The second village is the opposite - well protected by towers but with almost empty storehouse...

And of course it's not the universal tactics we are talking about, each mission has its own. And that's really weird. Because the game basically require you to know what to do at the beginning of the mission.

I recently did a bit of a ragequit with Police Quest VGA. I thought I still had my puzzle mojo but it seems my ability to play adventure games has degenerated since I was younger.

The Mummy ps1, though I like game, but I hated minigames, always run and then you got stuck and died.

I think it was couple years ago with DMC4. The backtracking level with dante and some lasers and a lot of jumping. I wouldn't ragequit if the game allowed me to quicksave, instead of repeating this shit over and over again.

I believe there was a boss fight afterwards and if you died there, you had to repeat the whole jumping shit.

I dont remember, how much I repeating that, but I was so angry :)

When I gave Super Street Fighter II a shot, specifically the arcade version. I have had a history with Street Fighter II and I could never get far in the game because of how hard it is for me. Other fighters like Tekken, Mortal Kombat, Soul Calibur, Dead or Alive, and One Must Fall: 2097 I am decent at, but Street Fighter II is so hard for me that it literally makes me hit my desk in rage and promptly quit.

I've temporarily ragequit Rogue Galaxy. The end boss has, like, 8 stages. The first one is normal combat with a full party, the other seven stages are each individual party member fighting the true boss's appendages individually. Including the guys you never used and never made high-level weapons for. And each boss fragments hits for half the health bar. And since they fight individually, there's no reviving from the team. And if you fail any stage, you have to do all the previous ones all over again.
Does Ni No Kuni have the same endgame setup, or have Level 5 got better?

La Mulana. I love what I played of it, but that game just got to a point where it ended up defeating me D:

Actually, make that Yoshi's Island...
