yeah some people still care I guess but I would still say that the Final Fantasy brand name doesn't carry the significance it once did. I remember when they announced that FFVII would be on the PS1 and it was huge news and it pretty much singlehandedly sealed the N64's fate. I just don't see that with FFXIII and how it being exclusive or not to the PS3 would've made any significant difference in sales.
I get what you mean and you are probably right but about the whole significance thing, I also think that FF feels less important now because I have gotten older and I don't really get overly excited about new games anymore. When I was a kid, I'd always anticipate Final Fantasy much more than I do now plus FF7 was the first Final Fantasy to come out in Europe and got a lot of people in the genre so it feels really significant but as far as sales go, I bet Final Fantasy still carries nearly the same importance as it did when FF7 or FF10 were announced. Both FF10 and 12 sold millions of copies and are probably among the best five selling PS2 titles so I'd say it's pretty clear that FF13 staying exclusive is pretty significant for sales. Now that 360 is getting it and a lot of other RPGs, Playstation doesn't really feel like the RPG console anymore, as it did in the past. Besides, gamers are dumb, they seriously buy consoles because of a single game. In PS3's case, FF13 was THE exclusive (apart from MGS4) so yeah, it was pretty important for Sony. This is going to boost 360's sales and surely will affect PS3's sales as well.
