I put off saying anything until now, because my emotions were conflicted, and "If you haven't got anything nice to say..." and all that jazz, but, I figure I'll toss my throwaway impression into the pool.
I went into FFXIII oblivious to the hype. I've been too busy with work to pay attention to any of it. I preordered the PS3 version, and my initial impression was that it was amazing. But then I played it for about ten hours over the course of a weekend, and slowly came to the opinion that it was the worst Final Fantasy game I had ever seen, wrapped in the best Final Fantasy graphics I had ever seen.
I was so disgusted with this game that I returned it to the store for a full refund (thanks for the free rental, EB/Gamestop). I never return or sell my games. I've only returned one game in 20 years, and I immediately regretted it. Congrats FFXIII! You're number two! But I won't regret you like I regretted number one, because I fully expect to buy you again off the clearance rack in a few months, because I'm an idiot like that.
My PS3 has become useless again, and I'm playing Tales of Vesperia to cheer myself up.
