The game development industry is not as big as web applications development, but is growing very fast all over the world. If you want to be a game developer or just develop some games, you must first decide what language you will use, because there is no solution for every language (at least not up to date or well maintained). The biggest solutions are Unity (C# , javascript and Boo) and Unreal Engine (C++). Other good solutions are LibGDX (Java) and PyGame (Python). So, if a Smalltalker wants to develop a game , they must select another language and adapt to that environment. Winter is a simple and fast to learn solution to this problem, so we can develop games using Smalltalk.
