The last 5 years of Game of The Year (Astro Bot (2024), Baldur's Gate 3 (2023), Elden Ring (2022), It Takes Two (2021), and The Last of Us Part II (2020)) are all nearly 45 GB+. All of them are incredible games spanning a vast series of game style (coop puzzle, solo platformer, stealth, ARPG, RPG) and animation.
Stardew Valley, universally acclaimed and not graphically intensive at all, still takes up nearly 2 GB of space.
Your view on games is not grounded in the reality of modern gaming.
In my experience a game worth playing never exceeded 1 (one) gig in size.
It is only incompetent creators that feel the need to bury their incompetence under gigabytes of irrelevance.
