Only the ignorant, selfish fanboys care.
FF started with Nintendo, then moved to Sony, and even then FF games were still being made on Nintendo consoles and portable-platforms. But OH GOD FORBID MICROSOFT GETTING AN FF AS WELL!
...
Fanboys... ruin the fun of gaming.
The only benefit I see from owning the PS3 version of FFXIII is that you can get it early (if you port it from Japan.) Even then, you need to understand Japanese. Hell, I've come across people who now hate FFXIII for the simple reason of it being on the 360 as well.
Gametrailers has a ton of these fools. Some of the FFXIII trailers before the announcement of a 360 version had a score of 9.5+ even solid 10s. Now after the announcement most of them have gone down to 8s. The Sony hardcore fanboys shouldn't be whining, we (the Sony console/portable owners) are getting TWO FF exclusives while Microsoft gets the FFXIII port. FFvXIII(maybe this will change too) and FFXIII Agito.
-Sigh- *Old Snake impression*
"Gaming has changed..."
