It's really weird how we are putting sequels in a "sequel nest", and others as DLC. I mean, we have shit like this since the dawn of videogames as a whole
I mean, Ultima 1 to 4 is basically the same game. Doom 1 and 2 are basically the same game. A lot of the Mega Man games are the same, even the modern ones. Far Cry since 3 doesn't look that different. Some could argue that CoD and Battlefield are two different games. And have you ever see sports games?!
There's a lot of technical shit we don't see it, and it's ok to judge some stuff, but I think people should ask for having a good time or not. New God of War and Zelda are not that different from before, but you know they are, and people worked they ass out to release those. So it's fine to ask for more, but don't be shitty about it
