I'm 15 now, 16 in November.
Anyway, I first got really into the Neo through the NGPC. I wanted a system since around age 12, and finally I got two (one for me an for my brother) and a few games with early Bar Mitzvah money. I remember ogling the reviews at Sector: NGP and Pocket.ign.com (they really liked the NGPC, you could tell) and thinking these guys were lucky to have played a NGPC.
I got my cab nearly a year ago (interestingly enough, I got my NGPC on Dec. 24, 2000 (long story short though I ordered it in like late August they never got a reshipment (they being express.com before they went mainstream/DVDs) and re-ordered with express dilevery through therage.com), and my cabinet I got on Dec. 24, 2002). I have 14 games for it. I rarely play my NGPC, but I'm never selling out. Oh, I have the MVS version of all the Neo games ported to DC in America, the DC ports are nice but the Neo versions are superior.
My love for the NeoGeo will never die, I'll be an old coot and still play my games.
