Well, my copy arrived in not too long ago. I was pretty quick to pop it into my PS3 to take a spin. This was awesome and yet annoying because everyone on my friend list was asking me how I got the game early! I guess the trophy descriptions being in English really doesn't help matters. (PSN's Neophoton, for those who are curious about interacting while I'm playing the game during EST on evenings.)
This is an impression based on 3 - 4 hours into the game. It's going to be slightly spoilerific, but only covers content that was slapped into the trailers.
(I try to keep things as spoiler-free as possible, but if you've been eying every trailer since the game's announcement roughly four years ago, then hardly any of it is spoiler-worthy. However, you've been warned.)
( You know, I'm amazed I'm so positive about this game given all the hate going around )The game's definitely worth the price tag in USD compared to most RPGs this generation, though, I give FFXIII that much credit to it. If you like the majority of FF games (X in particular), then I doubt you'll have FFXIII.
