I took on Unity and rebuilt parts of the fair from the content we have from the AAAS demo.
Unity is a very modern game engine. It supports all the new devices and platforms. It’s very convenient since authoring one game means you’ll be able to deliver on several platforms.
The downside of Unity is the lack of support for industry standards like LOD switching as well as an integrated node based shader editor. For things like that the users of Unity have to rely on the community. While there are tons of such micro solutions out there, there’s no way any game studio would rely on third parties to continuously support such tools on their own. “You get what you pay for” comes to my mind. And “OpenSource is freeware”…
We decided to keep going with Ogre3D mainly because of licensing issues. While all engines provide an EDU licensing scheme, that scheme is meant to be for educational purposes only. As long as you distribute your game for free, you might use the engine for free. But since our final deliverable is going to go into museums where people pay admission, we had to drop almost all of the engines immediately.
Here’s a few more images from my exercise
