Why are the final fantasy games so good?

[shio]

Final Fantasy series is not that good. It has a couple of great games, but the rest is only good/average.

FF1, 2, 3 - Archaic and outdated. Pointless to play them now.
FF4 - I heard it has a great story, but I can't remember well.
FF5 - Average at best. Outdated.
FF6 - Best FF story ever, with the best characters in a Final Fantasy. A must play.
FF7 - Aged badly, and it wasn't that great to begin with. Inconsistant story but the characters saved it.
FF8 - It has an inconsistent story but great cast (like FF7). Some of the mechanics hurt the fun. The character models are much better than FF7's though.
FF9 - Good cast, decent story. One of the best Final Fantasy.
FF10 - Average story, some boring characters with terrible voice-acting. The main character is possibly the worst one... ugghh. Do not play this. Good artstyle though.
FF11 - MMORPG, and a forgettable one. Just play WoW if you're interested in this type of game.
FF12 - Decent story, decent cast. A good and fun RPG, but not special or anything.

My advice is: Play FF6, FF9 and maybe FF4, FF12. Forget the rest.
