Oh man, another FF playthrough topic. Tag!
I've had a couple experiences with these games over the years. The Origins collection on PS1 back in the day was my introduction to both FF1 and FF2. I played a bunch of FF1 but never finished it there, and played about half an hour of FF2 before putting it down and never playing it again.
I then went through about 95% of the PSP version of FF1 which was great. Not sure why I never ended up finishing it though.
