lived ff1 on the nes (pure fighter or pure black mage for evil and expensive ), ff4 as f2 on the snes, ff5 emulated (job system was cool but took forever to build up) ff6 was the best of the series (memorable characters, beautiful soundtrack and well written plot).
nintendo fanboy in me says anything after 6 is crap (7 would have been better if the disk loading and cutscene magic didn't kill almost a minute each time)
ff mystic quest was meant more as a beginner rpg, for kids to get their feet wet a fun diverson if you want something to play and don't want to depend on mind bendiing strategy , and final fantasy adventure for gameboy wasn't too bad for ff on the go.
have ff4 for gba, finding it more of a fun challenge then ff2 for the snes, discovering the items removed from ff2, the bestiary and music player are kind of fun and the lunar dungeon made ff2 seem like sleepwalking
i want to get 6 for the gba, ebay is my only hope it seems tho :(
be nice if they were on a collector's edition on the gamecube, like the zelda games. only licensing and demand will tell
