Games like Resident Evil 2 remake are outliers. Most remakes are just bringing the graphics up to what the current tech can do
Remasters are usually just resolution and framerate increases
IMO if there are no core game changes than it is just a remaster.
Because a remaster is just that bring graphics to what the current tech can do… the core game… the core gameplay is untouched in remasters.
Remake you rebuild the core game including the core gameplay.
REMASTER: “The most basic way to explain what a remaster is; is that the remastered version is a revamped version of the older game. While adding new content to a video game remaster is not mandatory, the touched-up version can sometimes receive additional in-game content.
In addition, video game remasters typically mean classic video games with repainted visuals and in-game mechanics. Also, the in-game mechanics are optimized for the current generation of platforms the classic remaster is launching for.”
REMAKE: “As opposed to a remaster, a remake is a modern version of a classic video game rebuilt from scratch. Video game remakes make sure the game runs on the latest consoles or PCs. In addition, video game remakes are games reborn with entirely different elements; however, staying true to the original game.
In a video game remake, the gameplay is bound to change, with different elements added to the gameplay and the game’s environment, sometimes even new characters. However, as with video game remasters, remakes are altered up to the point that the game remains true to the original.”
Using a Remaster as Remake is just that… a marketing push to sell your game.
Unchartered: Legacy of Thieves, The Last of Us Part 1 are essentially remasters.
REmake 2, Final Fantasy VII Remake (the name was not choose due it being a remake it is story related… that is why the second part is called Rebirth) are remakes.
TL;DR version… TLOU Part 1 is a graphical repaint of PS3 classic to PS5/PC… the very very definition of remaster.
