What Smile Game Builder is
Smile Game Builder is paid Windows software for creating 2D and 3D role-playing games without programming. It includes more than 1,000 materials, covering characters, graphics, music, sound effects, buildings, and animals, and it lets users import their own characters and objects. Projects can be made for Windows directly. The optional Exporter for Unity DLC converts project files into Unity projects for output to iOS, Android, WebGL, and Nintendo Switch, with additional Switch requirements. SmileBoom says finished games may be distributed or sold without royalties or an individual license. The engine does not support scripting or programming languages for customization. A separate demo is available, but trial-made games cannot be distributed; the production version can open trial data. Purchase is through Steam, and minimum requirements include Windows 7/8/10, 2 GB RAM, OpenGL 3.0, and 800 MB storage.
