Most recent would be Psychonauts, I'd say. When I tried the demo, I was expecting a middling-to-bad platformer that attempts to make up for the half-assed gameplay with art design and story, which is essentially what I got. What I wasn't expecting was to hit the Wall before I finished the first, and this is important, training level.
You know what i mean by "the Wall." That one part in a game that is so badly designed that you wind up throwing the controller in frustration and yelling at the cat, "This is fucking IMPOSSIBLE!!!"
It's not impossible, of course. Just insanely difficult. It could be argued unfairly difficult, such as requiring precise, quick movements when the controls are so clunky that walking from one side of the room to the other is a chore.
I figured I would hit the wall in this game eventually, I just wasn't expecting it this soon. I soon stopped caring if I ever made it past that section, which would have been based more on luck than skill, and had to stop before I started wishing video games had never been invented just to keep this one from being made. What really sealed it for me was I realized that if I was hating the game this much so early, why should I plow through the rest of the demo, much less the full game?
This was surprising because I wasn't expecting to hate it this much. I figured I would not like it enough to buy it or things of that nature, but what really turned me off was that gameplay seemed more like an incidental consideration. Fans extol the virtues of the story and atmosphere. That's great. Double Fine should put their efforts into making movies instead, then. If they ever make a Psychonauts movie, I'll be first in line. But I do not want to ever play the game ever again. They can talk about all the neat set pieces or quirky situations that come up all they want. All I know is if the gameplay is not even tolerable. If I can't force myself to play it for one more second, then all of that is a colossal waste of effort as far as I'm concerned since I will never see any of it.
