I started with Pong. When I was in 7th grade my younger brother and I would save up our allowance and on a Saturday morning, walk about forty minutes, to Burger King for an early lunch and then hit the arcade next door. That's a fond memory for me. We had so much fun. Eventually moved to Nintendo, I loved Castlevania but it was too short. Tetris was cool too.
I graduated college and didn't touch a game until I was 29. Running my own business right out of college didn't leave me much time. I was at a crossroads and a friend of mine introduced me to the Wheel of Time. I loved that game. It was a first person shooter that had 40 offensive and defensive weapons that could be used in combos. I would log onto arena and people would instantly quit. I owned the arena. I reconfigured my keys and had key combos for all of my weapons. I was a guild leader there too. I loved the community.
Then I transitioned to Dark Age of Camelot. I nearly quit when the grind to fifty was so grueling. A friend convinced me to stay and I eventually was a guild leader there too.
@Merlin, I played on Pellinor server in Albion. My main character was a friar named Stosh. I loved that character until they nerfed reflex attack. I had a wizard, sorcerer and infiltrator. Those were some fun times. I played that game for about five years. I even met a girlfriend through it. I would never recommend that to anyone. After that I vowed to stay off online games. My addictive nature was not a good combo with the vast world of on line games and all of their content.
Over the years, games I liked were Sacrifice, Assassin's Creed I, Call of Duty Infinite Warfare, and Injustice 2. I played to make my kids happy mostly, but I get hooked and waste too much time on them. I can't start any others. I am so competitive that I need to conquer the entire game in all available options. I get consumed with the challenge and have to reach a level of proficiency that allows the game to get boring.
