4. Flexibility: You can adapt them for your own game logic/skins, especially in 2025 when rapid prototyping matters more than ever.

Tips for Using Free Assets Responsibly

• Check the license. Even “free” assets may have specific usage terms. One community thread reminds: > “Always check the license!” Reddit
• Use version control. When you import many free assets, keep them organised to avoid bloat.
• Optimise for mobile. Since you’re building mobile games (Android/iOS), make sure large free packs don’t hurt performance—compress, remove unused parts, and test.
• Update compatibility. Free assets may not always be updated for the latest Unity version—check compatibility and test.
• Customise & brand them. Using generic free assets is okay—but to stand out, tweak them to fit your game’s style and avoid a “generic” feel.
