If it wasn't MapleStory for me, it would have been SSBM.
I got invited to play Maple at an interesting point of my life. I'm sure it was toward the beginning of my sophomore year in high school, but I never played it seriously then. Just when I had the time to when I wasn't wasn't hanging out with my friends. I quickly made friends in game and that compelled me more to play the game. Soon enough I was juggling real life with playing Maple, trying to find a good balance. I didn't own my own PC at the time. But I knew my grandma had one, so I often spent the night at her house to play more. I guess this is the first sign. I didn't care for my grandma or anything. I just wanted a computer for Maplestory. Its funny thinking about it now, playing on an ancient Pentium 2 with a dial up connection in 2006. The computer ran like SHIT but I got to play. By the next year I had so many friends online that I practically begged my mom to buy me my own computer. I was still doing fairly well in school, so she caved and did it.
I got a full blown addiction. Its not like I just completely cut off the outside world. I still talked to my friends at school and played Smash with my friends at our Game Club, but all the time after school and Game Club was in purely dedicated to Maple. At this point, I knew my online friends intimately, made some serious deep friendships and even dated some girls online. By the second relationship, I had already to neglect my real friends, my schoolwork, and I spent more and more time playing Maple.
Holy shit I just realized I'm writing a blog so I'll skip some shit. When I graduated high school, I realized that I had no plan in life. Never thought about what I wanted to do or where I wanted to go. All I wanted to do was go home and play more Maple. So I did. I played Maple 3 years after I got out of high school. I stopped talking to all my friends. I stopped thinking about taking higher education. My computer was a crap box so I couldn't play any other game. The only reason I still had a social life while playing was because I still went to school. With school over, I had no obligation to keep up with anything. I didn't develop any skills. I forgot almost everything I learned. I lost all interest in almost anything and everything. I developed a serious depression that I'm still dealing with today.
I played Maple for a total of 6 years and it completely ruined my life (as of now). I don't blame anyone other than myself.
