If you interested in clans with mature players and are looking to have fun you might look into some the groups I'm following, just check my page; Off the top of my head some of the clans are panic disorder, over the hill gang, blue collar guardians, LoRM...and a few others. Beautiful Bastards is a group I joined but the clan I joined is called Panic Disorder, if anyone is interested. Though I will be playing with anyone whether they are clan-mates or not. Also If I turn out not to be your cup of tea(please feel free to delete/unfriend me), I can definitely try and introduce you to other fellow gamers from my list who might be more suited to your gaming needs.
