A good example of the limitations of PS2 vs. 360/PC can be easily demonstrated.

If you have both console types you will notice that on a PS2 if you change the background of your windows, it will take a good 3-6 seconds before your window background will actually change. On the 360 and PC, the background will immediately change to what you have selected.

Also what I have researched and have heard is that the current programming for FFXI does not support a 3 digit level number for your character. This explains level 99 instead of 100. It also leads me to believe that there are set variables for the game that would take a lot of time and effort to implement and change, not to mention you would probably have to do a complete reinstall of FFXI. This would suck for PS2 players. What ultimately holds us back via PS2 is the amount of information that can be displayed on screen at once, which is already bewildering considering our massive amounts of menus that reside in the background. Perhaps if some things were only viewable in mog house they could free up a bit of memory in order to implement some new jobs or something of that caliber. This is merely speculation on my part however, and I'm no FFXI programmer.

Just some insight for some of those who might not understand the memory (not storage space) limitations of the PS2.
