Actually, the original piece covered a few PC games as well, but I eventually decided it was a different kettle of fish and focused just on console remasters instead.
The funny thing about PC games is that sometimes you need remasters, and sometimes you don't. A game like Age of Empires II HD is awesome, because the original game can't run on Windows 7 without an incredible amount of jiggery-pokery. Conversely, a game like Baldur's Gate Enhanced Edition is cool, but there are already so many mods that beef it up for modern systems, I'm not sure it reinvents the whole experience.
I don't object to companies producing remaster for the Xbone and PS4, but I do object to them charging full price if the remaster only comes with one game. As I said in my God of War III Remastered review, God of War III is still a great game, but you can't justify a $40 price tag for a single title when you can buy the entire God of War series on PS3 for $35.
