Overview
RealmForge is built upon the Axiom 3D rendering engine, a C# port of the popular C++ OGRE Engine. It is written entirely in C# and built entirely upon a backbone of free and open-source libraries and enables development of free and commercial 3D games and simulations using .NET. RealmForge was featured on the front page of Software Developer's Journal as the first promising .NET game development solution and ranked as 9th top open-source engine in the DevMaster 3D Game and Graphics Engine Database. RealmForge is no longer under development but there is a fork of this project named ForgeRealm which is currently in development.
