SadConsole is a C#-based .NET cross-platform terminal, ascii, console, game engine. It simulates these types of programs and with it you can make ascii-styled games for modern platforms. At its heart, SadConsole is really a giant tile-based game engine. However, its object model is conceptually similar to a traditional console app.
These are the .NET templates for SadConsole. For more information, see Create a new SadConsole .NET project with the SadConsole templates.
