I wouldn't call this "guess-the-engine" - it's more like "guess-which-engine-the-artwork-I'm-showing-you-is-in".
IMHO, an engine should be viewed by it's features, not the artwork included in it's examples.
What I mean is, a true "guess-the-engine" thread would give you this information to guess the engine:
* DirectX 7 + Direct 9 + OpenGL Support
* Powerful particle engine and particle scripts
* Powerful material script system
* Supports PNG, JPEG, TGA, BMP or DDS files, including 1D textures, volumetric textures, cubemaps and compressed textures (DXT/S3TC)
* Dynamic LOD and polygon reduction tools
* Static geometry batching
* Advanced animation system including:
Blending of multiple simultaneous animations
Hardware accelerated animation support
Multiple interpolation modes (linear, spline, etc.)
Mesh morphing support (good for facial animations)
* LOD Terrain rendering
* BSP and Octree optimizations
* Billboard sprites
* Ribbon trails
* Automatic alpha-sorting of transparent meshes
* Media manager supporting the access of files within ZIP or PK3 archives
... and much more.
