Both Final Fantasy 9 and Final Fantasy 12 were fantastic swan songs to the PS1 and PS2 respectively. It's hard to pick one over the other. I think FF9 is a slightly better game, but FF12 is also fantastic and it was the last of the great Final Fantasy games. FF used to be my favorite series, but that stopped after 12. So, I guess FF12 was both the swan song for the PS2, and the Final Fantasy series too.
Could not agree more with these. 9 was such a great game with a great graphical style which showed truely what the PS1 was capable of, after above FF7.
In the UK, 12 actually came out after the release of PS3 as well. This is back when the PS3 was very expensive at the time and came with backward compatibility. It was around a time when I had left home for the first time and all I had was a old original PS2 with a tiny portable monitor to play it on. It still looked fantastic.
Agreed on the latter as well, while I have played the newer ones, none of them seem to catch the same feel as SNES, PS1 and PS2 generation FF games.
