Not sure about other remasters, but there's this really shitty thing virtually no one brings up about the God of War 1 and 2 PS3 remasters that honestly make them inferior to the PS2 versions:
In the PS2 versions, you have the option to choose between 4:3 and widescreen; widescreen mode does it in the worst way possible, cropping out the top and bottom of the 4:3 image. The PS3 versions, however, lack this option, being widescreen-only. Surely they changed it so the widescreen actually expands the original game's field of view? Fuck no, it does the same thing as the PS2's widescreen!
I played the first remaster for myself and found several instances of unfair bullshit that were completely fair in the 4:3 PS2 version. Like you know those wolves (among other enemies) that jump at you from a somewhat long range? In the 4:3 PS2 version, their range was just small enough so you could always see them preparing to jump at you; in widescreen, their range is larger than the vertical field of view, meaning they can and will jump at you from the top or bottom without warning. Again that's just one of the numerous cases that show the game was meant to be played in the original 4:3. Didn't bother replaying the second one, despite considering it even better than the first, because of how much new fake difficulty I had to deal with in what was originally a near-perfect game.
So yeah, if you want to play God of War 1 and 2, get the PS2 versions. They're even among the few PS2 games that support 480p.
