Creating a fair and balanced difficulty curve in video games is one of the most challenging aspects that every developer will face in getting their game to market. If you make the title too hard then you risk completely alienating certain portions of the player base as they fail to progress past certain points, and on the other hand, if you make the game too easy then you could end up failing to hold any interest.
People want a challenge, but they want it to be a fair one, and it's here where the difficulty comes in. How do you at once teach and push the player without it leading to a skill capped brick wall? The ways around this are numerous and would actually benefit their own article, but what we're interested in today are titles that seemed to get it right but then dropped the ball hard, before hoofing said ball right into our faces for good measure.
These are moments that turned experiences from being a casual but uphill climb into a scene more reminiscent of trying to climb Everest with your teeth. So brace yourselves as we're about to encounter some absolutely brutal difficulty spikes.
