Kenney Assets vs Quaternius

Kenney Assets is a downloadable library of game-development materials, including 2D sprites, 3D models, UI elements, audio, fonts, pixel art, and textures. Individual packs are free to download, while the Kenney Game Assets All-in-1 bundle is a one-time purchase at a minimum price of 19.95 USD. The bundle lists more than 60,000 assets, including over 1,200 sound effects and music loops, plus bitmap and vector fonts. Asset packs use a CC0 public-domain license, which permits commercial projects without requiring attribution. Listed formats include PNG, SVG, OBJ, FBX, GLTF, and OGG, described as compatible with all game engines. An optional launcher for Windows and Linux includes tools for tile extraction and combination, converting files and images, PNG compression, audio processing, and store-thumbnail creation. New packs are added frequently, and updates are free for existing bundle owners. Kenney does not support importing assets into specific game engines, directing users instead to its knowledge base or the engine's documentation and community.

Quaternius is a web catalog of game assets for personal, educational, and commercial projects. Its asset types include 3D models, animations, textures, source files, characters, environments, props, weapons, vehicles, and game kits, with packs covering characters, nature, animated assets, buildings, and vehicles. The QAL license is perpetual and royalty-free, allowing users to use, modify, and incorporate assets without attribution. It does not allow the assets themselves to be resold or redistributed as standalone files, packs, stock files, or templates. The Ultimate Animated Animal Pack contains 12 animals, each with more than 12 unique animations, in FBX, OBJ, glTF, and Blend formats. Models can be edited in Blender, and textures commonly use atlases. Free downloads cost nothing; paid Patreon tiers start at $10 a month.
