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.
Why Are Games Getting So Big?
Let’s face it—games today are more beautiful, more detailed, and more complex. That all takes space. Here are a few reasons why game sizes have exploded:
- High-resolution textures (think 4K and beyond)
- Realistic sound design with hours of surround audio
- Open-world environments that go on forever
- Uncompressed data for faster load times
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.
1. Call of Duty: Modern Warfare III (2025 Patch) – 300+ GB
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.
2. Microsoft Flight Simulator 2024 – 250+ GB
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.
As of 2025, with all the add-ons, global terrain packs, and weather simulation updates, you’re in for a hefty 250 GB+ install size. Pilots, bring an external SSD!
3. Star Citizen – ~220 GB and Rising
Still in alpha but acting like a full release, Star Citizen is big. Like… galaxy-sized.
This space MMO keeps adding planets, ships, and crazy amounts of detail. As of early 2025, it’s around 220 GB. And it’s only going to get bigger.
4. Red Dead Redemption 2 (Ultra HD Mods) – 200+ GB
Originally released years ago, this game is aging like fine wine. With 2025’s Ultra HD updates and mod packs, Red Dead 2 becomes a visual masterpiece.
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!
5. Forspoken (2025 Revision) – ~190 GB
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.
6. Cyberpunk 2077: Orion Preview Build – ~185 GB
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.
Expect to eat up about 185 GB on your drive, just to explore the future again.
7. Ark II – ~180 GB
Dinosaurs, high-end textures, and Vin Diesel. What more could you want?
Ark II builds on its already giant predecessor, with full island maps and biometric AI for dinos. That brings the total install size to around 180 GB.
Bring snacks. Loading might take longer than Jurassic periods.
Storage Solutions? Here’s What Gamers Are Doing!
When your games are the size of old hard drives, what can you do? Here’s how most PC gamers stay afloat:
- NVMe SSDs – Super fast and now more affordable
- External Drives for game backups
- Cloud Game Streaming to skip downloads entirely (if your internet is fast)
- Uninstalling games you’ve finished (yeah, it’s hard to say goodbye)
One smart move? Install your biggest games on separate drives. It keeps your OS drive cleaner and your load times faster.
Honorable Mentions – These Games Are No Lightweights!
Not quite top 7, but worth a shout for their massive installs:
- The Witcher 3 Next-Gen Mod Pack – 160 GB (with ray tracing)
- Baldur’s Gate 3: Expansion Bundle – 140 GB
- Destiny 2 + All Expansions – ~150 GB
- Assassin’s Creed Infinity Build – ~175 GB
These titles prove that even traditional RPGs and action-adventure games aren’t being shy when it comes to soaking up your SSD space.
How Much Space Do You Need in 2025?
If you’re planning to play a few of these titles, you better have at least:
- 2 TB of storage (bare minimum for multi-game installs)
- An SSD for faster loading and smoother gameplay
- Regular cleanup habits – like removing unused mods and patches
Seriously, it’s 2025. If you’re still gaming on a 500GB drive… you’re in storage danger!
Final Thoughts
Gaming has never been more immersive. But it also takes more space than ever before. Whether you’re flying over virtual mountains or dodging bullets in ultra-bloody realism, these behemoth-sized installs are here to stay.
Game wisely. Upgrade wisely. And always leave room for updates!
Your PC says “thank you.”
