Video games can be incredibly difficult. In fact, many gamers want their purchases to be hard rather than a quick and easy snore fest that doesn’t provide any sort of challenge. Often time they will require the player to experiment in the way they play the game or force them to learn new techniques to progress. Other times you might have to persevere with a tricky section that needs total concentration. Whatever the case you can normally either see what you have to do or come up with the answer naturally through gameplay.
Occasionally the developers will make their games hard in ways that aren’t rewarding or challenging but simply frustrating. These are the creators that have chosen the dark side, making their games purposely tough in unfair ways in the hope of infuriating you.
