As a veteran gamer, I rarely get a sense of thrill from games. With the exception of PvP (which I almost never play), games are typically very structured, and once you get the hang of it, you realize that there's a 'correct' response to every situation you are presented with. This is because your opponent is always an AI. This makes gaming very much about pattern recognition and formulating responses to those patterns. This ultimately leads to everything in any particular game becoming repetitive. If I'm able to learn and respond to the pattern, the game is easy. If not, the game is hard.
If the game is 'easy', it becomes boring quite quickly, though there is a certain pleasure in playing out the pattern over and over, trying to achieve perfection. On the other hand, if the game is 'hard', then it becomes aggravating. Not being able to grasp the pattern doesn't make the game a genuine challenge - it just makes it frustrating.
Therefore, rarely have I ever encountered anything while gaming that has given me anything close to the thrill of a challenge - of putting me under immense pressure, where I have to think hard, think fast, and respond to unpredictable new developments in a split second.
In an attempt to create a measure of unpredictability in games (and because I simply like helping people), I usually play a support class, whenever such things exist. This way, in multiplayer games, my job changes from only following the patterns of AI and set rotations of ability use to one where I am responsible for fixing the mistakes of my allies who are, after all, human, and inherently unpredictable.
But even then, there is always a 'correct' response to every situation, and there are usually not so many situations that I cannot memorize what to do for every situation that may arise. After all, there are only as many mistakes my allies can make as there are ways for them to fail to respond to the AI's limited pattern set.
Today, though, I was finally pushed to my limit and beyond. I finally encountered a situation for which I had to give 110% to overcome. I was under so much pressure that I, the veteran gamer who always knows how to respond to the situations I am presented with, became jittery and actually started hitting wrong buttons and casting spells on the wrong target because I was trying to plan and execute so many responses so quickly that I lost control.
In the end, unfortunately, I did not overcome the situation. I became so jittery near the end that, as is often the case when I'm under pressure and near the finish line, I start making silly mistakes. And as a result I ended up dying when the boss had only 1% of its HP left, which my last remaining party members were unable to finish before they went down due to having no healer supporting them.
But win or loss, it was one of, if not the best, moment of my gaming career.
