Years ago, when I was about 12 years old, I was addicted to RuneScape. Every evening after school, you'd find me cutting down trees, cooking, or venturing into the PvP zone for some awesome gear. One day, someone retired from the game by killing their character, which resulted in all of their items being dropped. I lucked out and snagged more gold than I could have ever imaged. I remember running around the house in joy.
In RuneScape at the time, there was another PvP zone where you could fight another player and bet gold on whether you would win. Now having "expendable gold" and false confidence, I dropped some big money on this PvP zone, and over the course of a day, I lost it all. I was devastated. I've never lost a ton of money in real life, but this left a really sick feeling in my stomach even in the digital world.
Reflecting on this experience, I feel it has actually benefited me. I've experienced the pain and risk that gambling can bring, and have never felt a need to do this with my actual money. To me, games can be a sandbox to learn life lessons without major consequences.
