In the past 5 years I only ever joined 2 clans, but quit both of them. One was made by a friend, and was actually quite large, but it became defunct after a couple months. The other was actually the Save sniping clan, but quit after a month as I joined to try it out and see what it was like... And it was boring. I was also a honorary member to several clans
Still, during MWR and Black Ops Wii I would consistently play together with others. Almost every time I would go online I would play together with friends, and while it was fun while it lasted, many of them had real life situations to look after and among other things. I didn't have to deal with it so much until my final year of high school, thankfully. Still, apart of that main group of people I use to play with, not a single one of them plays the series anymore. One is currently working and kind of in trouble money wise; another is working; another is working at his family's shop; another is helping out his family; another is playing PC indie games; and the other 2 are right now preparing to go to university. Me?
After screwing around for 2.5 years at my university I want to hurry up and graduate and get a move on with things. No matter how I see it, that time has long since passed for me. It all stopped around MW3's era.
