45. First one I played was FF6 on the SNES back in college. Bought it from the now-defunct electronics store chain The Good Guys for $70, I think. I made it to the game's second half, but had to go back to school, so I didn't finish it at the time.
Fast forward a bit and FF7 was next. Beat it, and that started me down the road where I went back to FF4, finished and loved that, and Chrono Trigger was next. A few years later, I'd marathon the entire series from 1-10, although I skipped 2 after not feeling it after playing a couple hours in.
I still look back very fondly on FF5. The music and job system are really special.
