The first FF13 game took a little bit to get rolling, but once it did was an excellent game. The second game starts going off the rails by making the central character someone who only shows up in flashbacks for the first game and it's really easy to make a wrong choice and be stuck in that game.
Then there's FF13-3, which shows Square-Enix didn't learn a thing about the disaster that was FFX-2. It combines the annoying outfit changes and thin central plot padded with annoying side quests of FFX-2 with always being on the clock and only being able to complete certain quests at certain times. Combat required near constant maintenance of different outfits and managing the abilities of each one, compared to the nice role system they had in FF13. It's Lightning and Lightning alone in this game, other FF13 characters make an appearance, but just so you can "save" them. What plot there is, is a complete mess.
By the end, I just couldn't bring myself to even care. A week or more might go by and I would have no desire at all to play the game. I forced myself all the way to the final fight, but after skimming a guide, realized it was just going to be a really cheap multi-stage fight, so gave up. If I want to see the ending I'll find it on YouTube.
Maybe it's my bias hating this game because on the surface it should be a pretty good game I guess. The problem is calling it a RPG is like calling Kim Kardasian a superstar and putting into the same namesake as a very specific type of experience people have come to expect is like showing up to a blind date and having it turn out to be your sister, sure it's a chic but WTH???? If this game out as as brand new series with no labels attached maybe I honestly wouldn't hate like i do, but trying to sneak it past brain functioning people as something that justifies the impact that the words Final Fantasy in it's title carry, y'all straight tripping.
