Right: Soon i wanna buy a FInal Fantasy game for Ps2, i'm in England so i don't know which one is the newest.

Which one would you say would be best , becausei don't wanna be dropped in without a clue on anything, but i want a relatively mdern version. What one should i get? My friend says get number 8 ( But that's ps1.... i want a ps2 one ) , what do you think?
