7. Background

8. Tiled and XTiled

9. Unity Options Few free and Open Source Only basic support

   Limited map size

10. UTiled Project Goals All Features of Tiled No Size Limit

    Modifiable (destructible environments) “The Unity Way”

    Physics issues better in 4.5, but still some remain No Zlib or Gzip compression support in Unity’s Mono Cannot access source image before import processor
