I used to love the FF series. FF2(4) is still my favorite with 3(6) a close second. After they started getting weird and preachy I began to lose interest. I did really like XIII and XIV, but after X they turned into a Japanese teen idol skin show.
Japanese games are excellent until they try to get "deep" and teach some philosophical principle to you. Look at Metal Gear Solid 1 vs 2. The first was excellent, the second's ending was a laughable theory on our government worthy of LABF.
