Exactly. Nintendo spent many years developing a sequel to Breath of the Wild, when they certainly could've gone for a cheap cash grab, and instead released an extremely high quality followup to a beloved game.
Not only that, but they delayed release for a year to fix bugs and polish TotK [1]. They deliberately missed the holiday '22 window for this! No one else seems to care about their games as much as Nintendo in terms of product quality.
The use of "just" here is classic underestimation of complexity or investment required. Technologists everywhere face this negative language from customers and other laypeople, and I expect many readers understand from first hand experience how insulting it feels. Please don't "share" that negativity with other creative arts.
ToTK makes BotW look like like an early developer build. While the base of the map is the same, they expanded it WAY beyond anything reasonable for an expansion pack. They have an below ground map that is the same size as the rest of hyrule and it is basically done just as a bonus to the rest of the title.
The depths is just inverted version of the same overworld height map, copy-pasted enemies and reused items from BOTW. It's simply yet another collectahon with bunch of puzzle shrines with physics sandbox. Not zelda game in my book. At least it did not copy paste the same boss with different skin 3 times this time however.
