I'm 16. I have all of the (official) American-released games aside from Leaf Green and Diamond, and I play about none of them. However, I just got back into Blue Version and I'm going to be training occasionally in there to up my team for the Elite Four (Blastoise, Zapdos, Magmar, Gyarados, Tauros, Machoke). I also think I'm at a reasonably good point in my Red Version (which I restarted as a result of my Charizard hitting lv. 70 and fearing that I couldn't control it)... probably halfway through Silph Co.
I don't so much play the GBA games unless it's to prepare for migration into Pearl.
I don't flaunt it, but I don't deny that I still play the games, and the people I hang out with either play it already, got back into it as a result of me reminding them about it, or don't care.
