Minecraft was the first game, someone on the "internet" gifted me. I was like "Why do you do that?!" and he was just like, because it's cool to play with you.
Minecraft was the first game I made long term friends from the internet in. I went on to play other games with my friends from minecraft for years. My first real relationship was with someone I met on Minecraft. I flew across the US to visit her multiple times in high school (working as a dishwasher to buy tickets). 7 years later I bought her and her child plane tickets to visit me (earlier this year).
Also Minecraft got me into programming in Java, which let to my programming career. So yeah... Minecraft has been a pretty big part of my life, even if I mostly stopped playing it in early high school :P
Ahhhh! Fond memories. :)
