Still wish it was possible to get a good preview of their actual tech rather than just their graphics. Couldn't care less how pretty some custom-tailored demos are. Only care about how easy it is to take their engine and build something with it ourselves. What are their API's like? What is their editor like? What is their scripting language? What kind of distribution/bundling features are included? Networking engine features? etc. Their site is pretty awful compared to something like Unity3D's, and they don't have a nice preview version of their toolkit for evaluation.
Soon as anyone can actually investigate Unigine itself rather than just their demos, then and only then will Unigine become interesting. They have like 3 games using it and almost no mindshare because their marketing tactics are based on id's, which are themselves based on "we're id" and not any kind of sane practice that applies to a company without such a legendary history.
