OK I voted before I read the topic, I thought it was asking which one I like best.
I voted 9, which is my personal favourite. I think that all 3 of the PS1 titles are equally suitable for new players, theyre all solid titles but all have their pros and cons. So out of those three I would suggest IX out of personal preference.
However, for a new player I would probably suggest Final Fantasy X. The PS2 means that its better graphically, and probably easier for a new player to get into as its not so much of a step back (not to say that the PS1 ones are bad).
XI is online, and its the only FF game that really doesnt hook me at all. It takes far too long to do anything, and you really need to take solid months out of your life to actually get anywhere. This is for hardcore players of either FF, or MMORPGs, in my opinion, and shouldnt be used to really get the first experience of a true FF title. The battles are more real time, which is different to all of its predecessors.
XII is newer, but it strays quite far from the traditional battle system (in a similar way to XI). Its not a bad game, but I enjoyed X more, and I think XII took longer for me to really get into.
So overall, I would reccomend X. If you like that, pick up its predecessors (and follow ups
) afterwards.
