Ever felt like your gaming PC might run out of space before you finish your snack? You’re not alone! In 2025, some video games are bigger than ever. Not just in graphics… but in file size. If you’re wondering what games are currently blowing up your hard drive, keep reading. We’ve got you covered with the biggest, baddest, and most space-hungry PC games of this year.

Now let’s dive into the biggest PC game installs of 2025. These are the titles that are asking you to clear out space—big time.
Yes, it’s still growing! With its latest 2025 update, Call of Duty: Modern Warfare III takes the cake. Between campaign modes, Warzone maps, and HD content packs, you’re looking at more than 300 GB of storage used up.
If you’re serious about playing, be ready to delete a few other games first. Or maybe even your college thesis.
This isn’t just a game. It’s a whole planet! Microsoft Flight Simulator continues to dominate with incredible detail. Cities, mountains, clouds—you name it.

But that beauty comes at a price: more than 200 GB if you enable all UHD textures and cinematic sound mods. Good luck keeping space for anything else!
Square Enix re-committed to this title in 2025, re-releasing it with major polish. The result? Stunning visuals and magical worlds that eat storage like it’s candy.
Its file size has bloated to nearly 190 GB. That’s a lot of particles and glowing effects.
CD Projekt’s latest step beyond Night City has brought a pre-release version of Orion. This new setting is massive—and so is the file size.
