I did it. I was 27 years old in Target. Played the THPS demo. I bought a playstation and THPS right then and there. I played every single one that came out after that except "Ride".
Oh, and I started skating when I was 13. Still skate a little today. I'm 42. I can't do nollie heels or 360 flips, but it's still really fun to skate with my son.
