I don't game on PC, but when I did, the storage consisted of a 250GB SSD for the OS and 1TB mechanical for the games. I certainly had nothing in the regions of 40TB, and neither does your average user. I own 234 games on Steam, but didn't have anywhere close to that installed at any given time.
I currently have the following installed on my Series X:
- BioShock
- Borderlands GOTY
- Cyberpunk 2077
- Dead Effect 2
- Deus Ex: Human Revolution
- Deus Ex: Mankind Divided
- Doom 3
- Elder Scrolls IV: Oblivion
- Evil Within 2
- Fallout 4
- Far Cry 5
- GTA: San Andreas
- Kingdom Come: Deliverance
- Metro Exodus
- Minecraft
- No Man's Sky
- Outward
- Resident Evil Code Veronica X
- Skyrim Special Edition
- Super Street Fighter IV: Arcade Edition
- Witcher 3 GOTY
- Wreckfest
