Sorry I wasn't clear. I was talking about the sort of jumping puzzles in Half-Life and Jedi Knight 2. The games where you have to repeatedly jump across pits and gaps. Such as in Half-Life, where the floor is missing in an area, and you have to jump from box to box to cross the gap. In Jedi Knight 2, there is a point where you have to jump on a mine cart to progress, and it's extremely frustrating, because it's easy to miss the jump. Finally, in Splinter Cell, on the oil-rig level, you have to jump to a certain pipe, and it's too easy to fall in the ocean. I'm not talking about jumping in Mario, where the controls are precise and the jumping isn't frustrating. I'm talking about games where you have to do extremely precise jumping, and the jumps are poorly designed.
