jMonkeyEngine is a game engine made for developers who want to create 3D games following modern technology standards. The framework is programmed entirely in Java, and aimed at wide accessibility and fast deployment to desktop, Web, and mobile platforms. It is not a visual “RPG Maker” or a drag-and-drop “FPS mod”. If you are comfortable writing Java code, you can rely on jMonkeyEngine as your next 3D game’s foundation.
The Gluon project is an open framework for creating and distributing games, supporting the flow of the idea all the way from the author to the player of the finished game. The current goal for the first stable release is to create games using 2D graphics. The reasoning behind this is that the niche for this type of visual is very large and so far untapped by specialized tools. In the world of 3D games there are solutions such as Unity3D, which provide a distribution system, but in the 2D game development world there are no tools to provide a complete ecosystem for creation, distribution, and feedback gathering. The three main audiences of Gluon are game creators, game players, and application programmers. Each of these are a user of one of the tools.
