Why do so many textures look like they are from a ps2 game?

[Ilan]

Its 2018 why is there a Mayan Pyramid on Hien's coat?

Why does the collar on Asahi's coat look like atari 2600 graphics?

Can we please get an HD texture pack option. Like, I shouldn't be read my computer monitor with my hands in cutscenes.

Why does someone state that its 2018 if the game is at least 5 years old?
