I'm trying to do that too, although there are new titles being added in. Like FF4's new sequel that is out on the consoles but not the PC, yet. I've played through the first four in order, waiting on five and six to be available. I bought seven and eight for the PC already. I really hope that nine, ten, ten part two and twelve get released soon, though, because those are the ones that I am most interested in (PSX and PS2 era) as I own them all but didn't get around to playing them on the consoles and would like to play them updated on a PC.
Kinds of hoping that some other classics like Parasite Eve get revamped too.
