It all comes down to amount of RAM an application can use. When I use photoshop for work sometimes it will eat up 4 to 5 GB of RAM because I work with huge files and multiple layers. The 32 bit version allows only 3.3 GB of RAM or something like that. The 64 bit version has no such limitation and for that reason the 32bit one is completely useless for me.

FFXIV in its current form wouldn't gain much from it because the game is designed around the lowest common denominator which is 512 MB RAM of PS3. Even a city is separated in two parts with loading screens so the game doesn't throw a lot of resources on RAM in big chunks.
