I am 27. I was playing since early 20's atleast. Been playing with the same account the entire time. Over 2500+ games. I've always been stuck at the 1100-1200 rating.
My skill level takes a nose dive down to 900-100 when I stop playing for a few months. But it can go as high as 1300-1400 when I really go hard at practicing and watching replays. Sometimes I love this game, other times I yell at the screen.
I do hope FAF truly is forever because I will play this game till the day I die or another game comes out to succeed it. After this many years playing, this is the only old game that I play.
