I've been playing since Red/Blue, but I skipped Black/White and BW2, because I anticipated a Gray version that never came, and by the time BW2 came out, I was just like "Whatever bro. I'm into other games right now."
Super-hyped for Pokemon X/Y so far, though. And I'm 24, if that's relevant to anything in this topic. --- "The best things in life must be taken... by force!" ~Captain Khan
