Eh… you can have high quality assets or you can have small size, but you can’t have both.

Game assets are typically some of the most heavily compressed assets there are (it’s often quicker, even from SSDs, to load a compressed asset and uncompress it than otherwise). There’s an entire middleware industry grown up around minimising asset sizes while keeping quality. 122 GB to me just screams “this game is fucking massive” rather than “this game is horribly unoptimised”.
