While Roblox seems inspired by the pixelated worlds in Minecraft, the program features plenty of original creations. Additionally, you can use Roblox for Android, and create, edit, or explore virtual worlds on the go. Since the program has a solid user base of over 100 million players per month, it comes with numerous free user-generated content options or worlds. The application lets you work with complex structures, collect resources and build architectural marvels on your PC.
