9, 7, ~~Lost Odyssey~~, 6.
8 has wonderful music and graphics but the story and characters are pretty much doodoo.
I played the entire XIII trilogy despite thinking XIII was a colossal failure on all fronts. I thought it was so uniquely, fascinatingly bad that I just had to see how they'd try to build on it going forward, and to Square Enix's credit, XIII-2 and Lightning Returns were infinitely better games, not that it necessarily amounted to much. I said 8's characters and story were doodoo but XIII was just abominable Squenix nonsense all the way
