I’ve added some more isometric/2d game engines to my Isometric Games Engine list list, below are 3 engines new to the list, but these have been around for awhile. Check them out:

• GEMRB Game Engine GemRB (Game engine made with preRendered Background) is a portable open-source implementation of Bioware’s Infinity Engine which was written to support pseudo-3D role playing games based on the Dungeons & Dragons ruleset. It should run on GNU/Linux, Microsoft Windows, OS X and possibly other UNIX derivatives. It is licensed under the GPL.

• Haaf Game Engine HGE is an easy to use yet powerful hardware accelerated 2D game engine. It is a full featured middleware for all who want to develop commercial quality 2D games rapidly and easily. It covers all imaginable 2D game genres: you could create everything from a simple puzzle to advanced multilayered platformer or strategy without even thinking of any non game logic code! And you don’t have to know anything about “window messages”, DirectX programming and all that stuff. Instead you can start developing your own game within 15 minutes!

• ika Game Engine ika (all lowercase) is a generic gaming engine geared (only slightly) towards making console style RPGs. It’s already been proven quite able to make puzzle/platform/what-have-you as well. You can read more about the feature list of ika here
