Virtual World Engines
From FAS Virtual Worlds Almanac
Hopefully, we plan on creating a semantic template system for virtual world engines, like we already have with virtual worlds. But for now, here is a list:
[edit] Open Source
OpenSim: http://www.opensimulator.org/
Paperworld 3D: http://paperworld3d.com/ Paperworld 3D is a game engine development tool for Flash, intended to be used to create 3-D games and multi-user applications, in virtual worlds and elsewhere. It appears to be open source, but expanded versions may not be free. You can find a demo at the site with further descriptions.
realXtend: http://www.realxtend.org/ realXtend is a Virtual World platform. The main focus areas are 3D Internet and user experience.
[edit] Proprietary
These are products which must be purchased or licensed.
Multiverse: MultiVerse (note: Multiverse claims to make their product available at no charge if they are not intended for non-commercial use.)
Olive: Forterra/OLIVE Brochure on Forterra Systems' web site
Uni-verse: Souldn't this be under "Open Source?" Uni-verse.org
Unity: Does this Unity Engine fit or is this "just" a 3D game making platform? and What is the difference?
UnrealTech: UNReal Technology home page
