Easy way that I keep running into is seen in games like DoA4 & others (this time it was Gears of War#1) who think that if you can make it through the rest of the game then you shouldn't be able to make it through boss fights or certain scenes where the difficulty & stuff you learned previously is sufficiently hosed meaning that the chance of getting past the boss/area is really low. Now I'm not looking for a free pass through the game ending if I make it through the other 90% of the game, just don't screw with the game to the point where after 20+ times of trying (and looking online for strategy to get past the boss) it doesn't make me want to put a controller through the tv, however finding the people involved & pitch their controller through their tv. Ramping up the difficulty makes me want to sell the game, not even rent the sequel & be entertained at playing Turok (full of stupid plot & silly yet fun dinosaur ginsu psycho fighting) for the 360 instead which is saying quite a lot when you look at how Turok went all blah middle of the road to many gamers. So remember game devs I'm more tolerant than other gamers but after 20+ tries I'm more than willing to suddenly ditch the game for something else while swearing at the TV.
