Let me hit you with a completely personal example:
There was this old RPGMaker game called Dragon Blade. It was a pretty stock JRPG thingie, but it was written on my first language, and since I was still a kid at the time and I had some troubles with English at that point, having a game I could completely understand pretty much blew my mind at that age. I played the game, and it was okay, even in retrospect. It had good characters, an ATB battle system that was constructed from the scratch (the original RPGMaker 2000 had static turn battles, the programmer of this game actually threw that entire system out the window and made a complex battle-system using in-game variables and sprites), and the story was engaging, so I had a blast with it and sunk about twenty hours into the game in one weekend.
Now, I told you all this so you understand the position I was in at the time: It was my first JRPG, the first time I had spent so much time on a game, and I enjoyed it immensely... and then that event came around...
The characters were in a town that was being razed by a demon, and they had to run away before it caught up with them. It was a fully interactive chase-scene where I had to lead the characters out of the burning town while the demon was following behind them with the same speed, so every moment of hesitation made it reduce the distance... and then the game started to play like a slide-show. Yeah, apparently the game's engine didn't like the 100+ flame sprites on the map, so it started lagging like crazy, and as you might have guessed, it didn't really help my chances in an intense chase-minigame...
So, I got caught. Retry. Got caught again. Retry. This time I ran into the fire too many times and the characters died from burns. Retry. Got caught again. And I did this for four hours for no avail until I snapped. This was the first and only time I ever lost my cool so bad that I threw my keyboard at the wall, but dammit, I was furious about it, especially after I have spent so much time on it. In the end I managed to finish that game once the developer put out an effects-free version so that people without high-end computers could also finish the damn scene, but that game still remains the only title that could ever make me rage hard enough to actually throw something at the wall...
