I have'nt played any of the older FF's but i've played FF X and now I'm playing FF X-2. my freind said that the only place you can find the oldr ones is on ebay or used at pawnshops an such.
Beh, actually I'm finally playing X as well. Just beat Yunalesca yesterday. Kinda complicated keeping up with 2 Final Fantasies at the same time having like 2 hours a day to play, but it's quite interesting =]
And hell, say what you will but I actually like X pretty much. Like as much as VIII, to say the least. Can't really see why so many people say bad things about its story and characters... It kinda has a special feel of its own with all the Sin/fayth/aeons/summoners/jecht/auron/tidus stuff.
I may as well try playing X-2 again after I beat X. The first time through X-2 I got stuck on the Magus sisters fight for not leveling up properly before going to the farplane - -" Didn't really have the patience to keep up with the game... But now that I know the origin of the characters I think it should be a more interesting experience...
And for you guys who are waiting to play XII, hell, I ain't one to brag about one game being oh-so-great but man, I tell ya, you should play this one SOON. There are some very special things going for it that I can't really explain, but maybe that's just cuz' I like Vagrant Story so much.
