Where can i get FF games?

hey, im new as of 5 seconds ago, but im a huge FF fan (maybe not as big as some of u out there), and i've been trying desperately for the past hour to find FF ROMS....

i've found that 1-6 are decently easy to find, as they are on the SNES and all, but i've had ABSOLUTELY NO luck finding 7 and 8 especially (i've seen 9 once or twice). i hear 7 is the best out there and i'd REALLY like to play it.

Also, according to you guys, which are your favorites and/or most fun for you to play? the first FF game i ever bought was FFX, and i've played FFXI, as well as FFT Advance. some say FFX was good -- others say it sucked -- i loved it (i didnt bother w/ X-2 cuz i heard/saw it was pretty dumb). so what else is good? tell me what you liked about it (ie. the plot line, characters, graphics, classes, characters, replayability, etc.)

I sincerely hope those of you more old-school than I can assist me and guide me to the better of the FF games! Thanks ^_^

EDIT: Oh yeah, also, if some of these games arent available on ROMS (like, maybe 7 and 8 arent [?]), where could i buy them? i havent seen the FF title in stores for a while, especially the old ones. and if they are available on ROMS (which is preferred) where can i get them? -- Thanks again =D

so.... no one actually plays the old games any more...?

Don't double post, use the edit/delete button instead.
