1) First Final Fantasy game you played
Final Fantasy 6
2) The Final Fantasy game you preffer
Final Fantasy X
3) Which Final Fantasy games have you played?
I have played them all. But the ones I finished were:
Final Fantasy IV, Final Fantasy VI, Final Fantasy VII, Final Fantasy IX, Final Fantasy X, Final Fantasy XII(barf) and Final Fantasy XIII.

You are missing some great games... FF IX still holds greatly.

The first Final Fantasy I experienced first hand was FFIX. It was at a friend's house and I wasn't really into gaming at the time due to lack of available options at home. Looked fun. Then I made a new friend later who was a total fan of FF and owned a PS1 and PS2. He let me borrow his PS1 to play FFVIII at home. It was quite fun and to this date I'm really fond of the game, even though gameplay wise it is one of the worst in the series. But I loved the world and the music and I still do, which is why it's still in my top 5. At that point I became interested in the series and started to play all of the NES and SNES games via emulator. I also at some point played FFIX thoroughly but I don't know about the timing on that one. After that I bought a PS3 to play FFX and FFXII and finally FFXIII. the latter two are still very high up in my list while FFX not so much.

Long story short, FFIX is the best FF game and it will stay that way forever until FF goes back to its roots.

Reminds of this thread I made a few aeons ago about first Final Fantasies being the best... I'd say your question was more to the point but there might be some interesting answers to find.

1)Final Fantasy Tactics Advance. First numbered entry would be the GBA version of 1 and 2.

2) Numbered would be Final Fantasy 10. But I did thoroughly enjoy Tactics Advance, IV and XIV Realm Reborn.

3) Oh geez. You want me to list all of them out? Let's just say most of the numbered and spin offs and call it a day.

The first one I played was IV, back in the SNES, but my favorite is XII with X a close second. I played almost all of the mainline ones except for III, XI, XIV.
