• CC0 (public domain)

• CC-BY, CC-BY-SA, OGA-BY, or GPL/LGPL — giving varying levels of requirement (usually attribution, or “share alike”)

✅ Best Practices When Using OpenGameArt

1. Check the license for each asset
   Always verify that the license allows commercial use and note any obligations
   (e.g., attribution or share-alike).

2. Record attribution details
   Save the following for every asset you use:

   • Name of the asset
   • Author/creator
   • License type
   • Link to the original source
     This makes it easier to include proper credits in your game.

3. Prefer safe licenses
   Use assets under CC0, OGA-BY, or CC-BY (with attribution)
   for the simplest usage in both commercial and closed-source projects.

4. Be cautious with GPL / CC-BY-SA

   • ShareAlike (SA): requires derivatives to use the same license.
   • GPL: often conflicts with closed-source or proprietary games.
     Use only if you fully understand the implications.

5. Bundle license info with your game
   Include a file or folder in your game distribution listing:

   • All used assets
   • Their licenses
   • Full license texts (if required)
     This keeps everything transparent and legally safe.

⚠️ Caveats & What to Watch Out For

• License matters per asset
  Just because the site is “free assets” doesn’t mean every piece is CC0.
  Each upload has its own license.

• CC-BY / CC-BY-SA / OGA-BY require attribution

  • CC-BY: You must credit the original creator.
  • CC-BY-SA: In addition to attribution, derivatives must carry the same license.
  • OGA-BY: Similar to CC-BY but removes certain technical restrictions.

• GPL-licensed assets are tricky
  GPL is designed for software, not art.
  Using GPL assets in a non-GPL (closed-source) game can create licensing conflicts.

• Technical restriction clauses
  Some licenses (like CC-BY) include clauses against DRM or technical limitations.
  OGA-BY was created to avoid these issues.

• Safe choices for commercial games
  Stick with CC0, OGA-BY, or CC-BY (with proper attribution)
  to avoid complications.
