If you are an Unreal Engine game developer, Epic just announced a pretty sweet give away. They just released $12,000,000 worth of art assets from the 2017 MOBA Paragon. The assets include 20 AAA quality characters, fully rigged, textured and animated, ready for game deployment. Additionally they released 1,500+ assets used to develop game levels.
The assets are usable without condition so long as you are using Unreal Engine. If you are using a different game engine you have no rights to any of these assets.
