So growing up, I never really did good in school. I went through a lot of emotional stress due to my parents expectations as well as bullying from other kids, so online gaming was my way of getting away from the world and having a good time. 
My time spent online playing games like Graal Classic iPhone and other MMORPGs was absolutely amazing. I had a blast, I felt like I was accomplishing things(lead a top 10 tower capturing guild at the time),felt meaningful, and overall it was exciting. Gaming filled a void in my life that made it better.
Now I graduated highschool, have a job, attending college, and overall feel like I have things that make me feel purposeful. Playing games just isn't as fun anymore. Maybe its because I found other things in life, or maybe its just because I grew sick of games in general.
My addiction with Archeage led me to end up dropping 2 college classes due to falling behind in them. But I then focused on my remaining 2 classes, and ended the semester with a 4.0 GPA and received several rewards(ironically).
Back in highschool, when I grinded in an MMO, I felt like I was accomplishing things. Now, I feel like I'm wasting precious time that I'll never get back. There's still times I find games fun, mainly when new content is fresh(such as a new dungeon coming out or new MMO) but I burn out fast now. Each new MMO makes me hopeful, but I always get bored shortly after. Once you've played through all the content the game has to offer, it just gets repetitive-and game hopping isn't really that fun.
I feel like if I focus my time on my studies I might be able to maintain a 3.5+ GPA and feel a bit of self accomplishment. Also if I take an extended break, maybe other MMORPGs like Everquest Next and Black Desert will be more fun when they come out.
Thoughts? 
tl;dr: Gaming isn't as fun for me anymore, feel like I don't need it as much, but I'm kind of addicted.
