Obviously, you dind't get the point.
SE has made it clear they have no desire to port the decade old FFXI to the PS3. They want FFXIV to be the MMO title built specifically for that platform. They are NOT going to invest in a re-write for FFXI for the PS3. They didn't even do that for the XB360--at it's core, it's the same game across all three platforms, only different versions of the wrapper (ie, POL client) specific to the platform.
To make FFXI run on the PS3, currently all that is needed is compliant emulation--so, technically it can already run on the PS3 and SE does not feel it is worthy of a rewrite for a whole new shell to run it on the PS3, as there is already a means to do it.
Edit:
And as Frank said...PC gaming or console gaming....the experience is more or less the same when it comes to FFXI, with the exception of better quality graphics (and soon, more up to date UI features). I have played FFXI on my PC with a PS2 controller since day one. There are even PC controllers that emulate PS2 (Logitech, MadCats, several companies have them).
Edit2:
And again.. you keep coming back to your PC not being built for gaming. Just what exactly about your PC is holding you back from being able to play FFXI? You keep saying that, yet you have yet to state this specifically. It doesn't take a gaming rig to run FFXI. Intel Graphics have been able to run FFXI for almost 8 years now. It can run on netbook ffs....most any an APU system from the past 4 years or so can run it. My IBM laptop (an office machine, mind you, built solely to demo mock websites and apps on it) would be able to run it if I only had a better ATI card in it. If I still had access to the office's docking station, I could drop in one of my old PCI cards and run the game--it meets all the specs except for proper hardware TNL support.
FFXI will run on a PENTIUM III System. We are talking about technology that was in the mainstream BEFORE FFXI was released for PC (P3-800 MHz were released in 1999). So, again....just what is it about your system that prevents it from being capable of running FFXI?
