C# .NET simple RPG role-playing battle game. Designed as an example of using the Expression Builder pattern with method chaining and progressive interfaces in C#. Demonstrates a basic internal domain specific language design. Also lets you kill some monsters too!
A 2011 teaching example showing the Expression Builder / progressive interface pattern in C# — you chain methods to construct an RPG character and the interface types restrict what methods are available at each step. It's for developers who want a concrete, runnable illustration of that design pattern, not for anyone building an actual game.
The progressive interface trick (ICharacterBuilderAge → ICharacterBuilderClassType → ICharacterBuilderStats) is a clean demonstration of how to use C# interfaces to enforce call order at compile time rather than runtime. The project is small enough to read in 20 minutes, which is the right size for a pattern demo. The RPG framing makes the abstract concept (DSL construction) feel tangible.
Last touched in 2011 — targets what is almost certainly .NET Framework 4.x and won't build without changes on anything modern. The README is just a license file; there is no explanation of what the pattern is or why you'd use it, so a reader who doesn't already know about Expression Builder gets no help. 32 stars over 15 years suggests this never found its audience. There's no test coverage, so the 'correct' usage of the fluent chain is only demonstrated in Program.cs by example.
