God of War . Prince of Persia . Splinter Cell . ICO and Shadow of the Colossus . Tomb Raider . Metal Gear Solid . Zone of the Enders . High-definition collections of the latter two are yet to come, but we've already seen the others. And there are individual PS2 titles that have enjoyed new life in the HD world, like Beyond Good & Evil .
We've also recently heard that Square Enix is currently looking into HD technology testing. When you combine this with the enduring fans who maintain that a Final Fantasy VII remake would be the second coming, you've got a strong case for a Final Fantasy HD Collection . Of course, if it does happen, it may not involve the PS1 classics. Konami has said they couldn't include the original MGS in that MGS Collection for various technical reasons; it's why we're getting MGS2 and MGS3. For an HD remake, it really needs to be a PS2 game, or so it seems. But hey, there are several titles that are eligible.
Final Fantasy X , Final Fantasy X-2 , and Final Fantasy XII could receive the high-def overhaul (FFXI seems out of the realm of possibility, but does anyone really care?), and that's good enough for the fans. At least, for now. Above all else, Square Enix could use a boost, and these collections don't exist for no reason; they do help turn a profit, even if it's a relatively small one. Besides, I think – I think – Square Enix finally understands that some fan service is in order to keep their fans. …some of those fans feel like they're suffering, ya know. Just give 'em a collection.
