6,7, and 8 are my favorites and the most mature with just a little grit. I never liked 9, and tried over and over to play it; too much fantasy for me, and too goofy at times. If you like teen drama anime's then ff9 might be for you. That shyt was like Dawson’s creek with magic and swords.
I’ve also tried 10 since it’s originally dropped. I can’t get over the whiny ass voice of the main protagonist. I’ve read a summary of the story, and preferred it that way lol. It was pretty advanced enough to get through when it first dropped. Blitz ball was the only redeeming thing about it for me.
Tactics was really cool and a favorite amongst the community. Also check out xenogears, vagrant story, and suikonden 2 (I think I spelled it right). Those were all favorites by squaresoft.
11 is a waste. 12 was really dry. The world is bland and it’s hard to find a reason to want to keep checking bounties. 13 is a hallway simulator. The first 45 mins were bruh-man running down a single hallway and reading ancient texts. By the time you get to the possible start of the game, you turn it off and rethink life. Some people really like 14, it’s online I might try it one day.
15 was cool at first but dries up real quick. I think it would have been better if the camera wasn’t free and the world wasn’t open. I enjoyed it for a few days then took a break. I forgot to pick it back up until months later. Once I started playing again I realized I didn’t have a reason to finish.
6-8 is like the WWF attitude era or the 1980’s-2001 NBA. Everything after is like the family friendly WWE or or no hand check, and no tolerance fighting policy NBA. Can’t hurt to try them all though.
