Make of this what you will.
- Better colors--It may be possible to fix this by mucking about in settings, but the default settings for both the PC and Xbox 360 versions have colors that are very washed out. After getting accustomed to playing on the PlayStation 2 for a while, on other platforms it will become difficult to see the difference between the white text of /say and the red of /shout.
- Better 2D--With this game being so menu-heavy, it doesn't take long to notice how well the PS2 renders them as compared to other platforms. Even fonts and icon and item art look better, most visibly because of the lack of the thick, black borders on everything on the PC and Xbox versions. Granted, the PS2 is probably the reason why it looks like the art on other platforms look drawn with a Sharpie, but the end result is the same.
- No mucking about with gamma--This deserves to stand apart from the first "better colors" point above. It "just works," in contrast to the other two platforms. Most damningly, as the original update notes themselve state, gamma settings on the PC version need to be changed between full-screen and windowed modes.
- Smoother framerate--Your mileage will obviously vary on the PC, but the framerate on the PS2 is typically higher than the Xbox 360 in the same situations, and I don't pretend to know why. And I'm not even talking about using the Xbox in HD mode.
- Smooth docking--This is a graphical glitch that has plagued the PC version since launch, and was ported over to the Xbox 360. Docking ships and airships aren't actually supposed to suddenly jump to the right during docking scenes. PlayStation 2 players know this.
- Different clipping algorithm--This is most noticeable walking along Drogaroga's Spine in Meriphataud Mountains, but can be seen anyplace where a mountain can suddenly snap into existence on the horizon as the camera moves. The PS2 instead will draw any surface closer than the clipping plane, even if it's only part of a complete object.
- No grids in the sky--This is most noticeable in overcast skies, as is usually the case in Xarcabard.
- No "Xbox Camera Disease"--Most noticeable in a Mog House, where moving the camera in third-person can cause sudden seizures.
- No ATI or nVidia video drivers--Self explanatory.
- No zoning lag--As just about every Xbox player knows, there is a ~1 s hang soon after changing areas, each and every time. You may get desensitized to it over time, but you will notice it if you change platforms and come back, and it will drive you crazy.
- Discless play--For a few fleeting days, it was possible to play the Xbox 360 version without having a disc in the drive. No more. Meanwhile, launching the PlayStation 2 version from the HDD was originally the only option. Booting with a CoP or later disc is simply a luxury that allows for faster startup times.
- No disc read errors--Not only are discs not required, they've yet to actually become a problem on the PS2, in stark contrast to the Xbox 360.
- Full sound during character creation--Hear the running Tarutaru gasp to catch her breath while dancing! Hear the Galka scream to the heavens as he pounds his fists on the ground! Wonder why you can't hear these things on the PC or Xbox. Also wonder what other sounds may be missing from gameplay itself.
- PlayOnline yell--Every time you start.
- /shutdown does what it says--There is no need to hold your breath while signing off, hoping the Xbox Dashboard loads successfully; this command actually shuts down the PS2.
