That’s also assuming the remastered version is the exact same as the original, but with only graphics update.
For example, Resident Evil 2 remastered has some major differences compared to the original. Some of them being the camera angle and free range aim.
Yeah, that's right. Sometimes "remastered" is just about graphics and sound, and sometimes controls are diferent (which can make huge difference in gameplay quality) and sometimes it's like a total overhaul, with some features added/removed resulting in almost a new game, just looking similar. In the latter case, I wouldn't really consider it 'remastered', but rather, a new release, or huge service-pack/patch-pack, say i.e. FF7.02 :)
