Has Sony said anything about Playstation One games on PS4 yet? I wouldn't rule it out because PS3 can still play PSOne game discs, I don't see why 4 couldn't have whatever software takes care of that, or an adaption of it. Be a bit of a shame if it couldn't.
I like Final Fantasy 8, 9, and 10, don't care if anyone else doesn't. 9's not my favorite but I've grown an appreciation of it and would defend it the hardest. As for Tidus, the amount that I do not like him is less than the amount that I do like Yuna, Rikku, Lulu, Auron, and the Aeons, each individually.
COD Ghosts. Yes, there's a dog, but not instead of a female character, there's just a dog, remove the dog and a girl will not appear, there just wouldn't be a dog. On top of it, any amount of *new* gimmick or element I think far out weighs cosmetic changes. A woman character in a COD game seems like a very reasonable thing, why not have one, but in this context people are upset that a dog is in the game instead of a woman? Having a woman character wouldn't really change the game any though she would play the same as a guy, where as having a dog would change things. There are seemingly going to be new gameplay elements in Ghosts based on the dog - as stupid as the dog is going to be, as silly as it is to have a dog, whatever they do it should add a new element to the game, one that shouldn't hurt any, be happy for that. Don't be upset that there's now a dog and still not a woman, be upset there's still not a woman, but don't blame the dog.
