In the early 2000s, a full retail game on DVD rarely exceeded 8GB. Today, it’s common for a single title to demand over 150GB of storage—with some stretching beyond 200GB. Games like Call of Duty: Modern Warfare II, Red Dead Redemption 2, and Cyberpunk 2077 require more disk space than many laptops shipped with just a decade ago. This explosive growth in file size isn’t arbitrary. It reflects a convergence of technological ambition, artistic expectations, and evolving development practices. Understanding why games have become so massive reveals not only how far the industry has come but also the trade-offs players and developers now face.
The Evolution of Game Assets
At the core of ballooning game sizes is the dramatic increase in asset quality. Modern games rely on high-resolution textures, detailed 3D models, expansive environments, and complex animations—all of which consume significant storage space.
Textures, for example, have evolved from 512x512 pixel images to 4K (4096x4096) or even 8K resolutions. A single 4K texture can be over 50MB when uncompressed. Multiply that by thousands of assets across cities, characters, weapons, and vehicles, and the numbers add up quickly.
Audio is another major contributor. Older games used compressed or MIDI-based music and short, looped sound effects. Today, games feature full orchestral scores recorded in professional studios, dozens of hours of voice acting, and spatial audio systems that adapt in real time. For instance, The Last of Us Part II includes over 60 hours of recorded dialogue—more than most TV series seasons combined.
Bigger Worlds, More Content
Open-world design has become the gold standard for AAA titles. Developers now build vast, seamless environments meant to feel alive and immersive. These worlds aren’t just large—they’re densely populated with interactive objects, NPCs, dynamic weather, wildlife, and side activities.
Take Red Dead Redemption 2. Its world spans multiple biomes—mountains, swamps, deserts, towns—each hand-crafted with unique flora, fauna, and architecture. Every tree, rock, and animal model contributes to the total footprint. The game’s base installation clocks in at around 110GB on consoles and over 150GB on PC due to higher-res assets.
Additionally, modern games often include multiple endings, branching storylines, and extensive quest lines. While this enhances replayability, it also means more cutscenes, dialogue trees, and environment variations—all stored locally and contributing to size.
“Players expect cinematic fidelity and endless things to do. That richness comes at a cost—storage space.” — Marcus Lin, Senior Environment Artist at Obsidian Entertainment
Compression and Installation Trade-Offs
One might assume better compression would keep sizes under control. And while compression technology has improved, developers often prioritize performance over size savings.
Many games use lossless or lightly compressed formats to reduce CPU overhead during gameplay. Real-time decompression can cause stuttering or frame drops, especially on consoles with fixed hardware. As a result, studios opt to install larger files upfront to ensure smooth streaming of assets as players move through the world.
Additionally, platforms like PlayStation and Xbox allow developers to optimize data layout on SSDs. Fast read speeds mean less need for aggressive compression, encouraging teams to store higher-quality assets directly. The shift to SSDs in the PS5 and Xbox Series X/S has, paradoxically, led to bigger installs because developers no longer need to downgrade assets for mechanical hard drive limitations.
| Era | Avg. Game Size | Primary Storage | Key Limitations |
|---|---|---|---|
| Early 2000s | 1–8 GB | DVD | Disc capacity, low-res textures |
| Late 2000s | 8–25 GB | Dual-layer DVD / Blu-ray | Loading times, asset streaming |
| 2010s | 30–80 GB | Blu-ray, digital download | Bandwidth, HDD speed |
| 2020s | 80–200+ GB | Digital, SSD-optimized | Disk space, download times |
Development Practices and Bloat
Game development pipelines have also contributed to size inflation. Modern engines like Unreal Engine 5 and Unity support high-fidelity workflows out of the box, making it easy—even default—to import ultra-high-res assets. Without strict optimization protocols, teams may leave unused or redundant files in builds.
For example, a character model might include multiple versions of clothing, accessories, or animations that are only used in specific cutscenes or alternate paths. If these aren’t stripped during final packaging, they remain part of the install. Some estimates suggest that up to 10–15% of a game’s installed size consists of unreferenced or obsolete data.
Moreover, localization multiplies file size. A game released in 12 languages will include separate audio tracks, subtitles, and UI elements for each. Voice acting alone can double the size—especially if every line is recorded in multiple languages with full emotional range.
Consider Cyberpunk 2077: its initial release required 70GB, but with all language packs installed, it ballooned to nearly 120GB. CD Projekt RED later introduced an option to download only selected languages, giving users control—but highlighting how much space was previously wasted.
Real-World Example: Installing “Starfield”
When Bethesda launched Starfield in 2023, players were stunned: the base game required 135GB of storage. For context, that’s equivalent to about 27,000 high-resolution photos or over 30,000 printed pages of text.
Why so large? The answer lies in its scope. The game features over 1,000 planets, each with procedurally generated terrain and hand-tuned points of interest. While not every planet is fully detailed, the engine must store core assets—rock types, atmospheric shaders, building templates—that are reused across systems. Additionally, the game includes a full voice cast for every NPC dialogue line, totaling over 60,000 recorded lines.
One player, Sarah K., shared her experience: “I have a 512GB laptop. After Windows, apps, and documents, I had about 200GB free. I downloaded Starfield, and suddenly I was down to 60GB. I had to uninstall two other games just to keep it. It felt absurd—like the game was taking over my life.”
This scenario is increasingly common. Gamers are forced to make choices not just about what to play, but what to delete. Cloud saves help, but they don’t solve the fundamental issue: local storage is becoming a bottleneck.
What Can Be Done? Practical Solutions
While we can’t reverse technological progress, there are ways to manage the impact of ever-growing game sizes.
Step-by-Step: Optimizing Your Gaming Storage
- Assess your current setup: Check total storage, available space, and usage breakdown across drives.
- Prioritize SSDs: Install frequently played games on NVMe or SATA SSDs for faster load times and better performance.
- Use tiered storage: Keep older or infrequently played games on external HDDs. Move them back when needed.
- Selective downloads: On platforms like Steam or Xbox, choose which language packs or components to install.
- Enable cloud sync: Ensure save files are backed up so you can reinstall games without losing progress.
- Monitor updates: Patches can add gigabytes. Some games grow significantly post-launch due to added content.
Checklist: Managing Large Game Installs
- ✅ Audit storage monthly
- ✅ Uninstall games after completing them
- ✅ Use external SSDs for portability and speed
- ✅ Disable unnecessary language packs
- ✅ Keep operating system lean
- ✅ Schedule downloads during off-peak hours
Looking Ahead: The Future of Game Sizes
There’s little indication that game sizes will shrink. In fact, trends point toward further expansion. Virtual production techniques, photogrammetry (scanning real-world objects), and AI-generated content all produce rich, detailed data that demands space.
Cloud gaming offers a potential solution. Services like Xbox Cloud Gaming, NVIDIA GeForce Now, and PlayStation Plus Premium stream games directly, reducing the need for local storage. However, they require consistent, high-speed internet—a barrier for many regions.
On the development side, smarter asset streaming and modular downloads could help. Imagine downloading only the region of a game world you’re currently exploring, or choosing between “quality tiers” at install time—similar to video resolution options in streaming apps.
Some studios are already experimenting. Ubisoft’s Star Wars Outlaws uses scalable texture packs, allowing players to choose between smaller installs with lower-res assets or maximum fidelity. This user-controlled approach may become standard.
