The AlphaGenesis project aims to create both a high quality, strategy oriented, SNES style turn based RPG, and an engine for building top down perspective 2D games. I have been writing the engine in my spare time over the past few years. It currently contains a game client and map editor. It is mostly complete as an engine, but there are a few features I still plan to add.
