Features

General Features

Object-Oriented Design, Plug-in Architecture, Save/Load System, Other:

•	A math library - for fast vector calculations (will also include support for 3D-now and SIMD).
•	An extended polygon based math library - for things like clipping, inclusive polygons, polygon projection etc.
•	A zip file system - for easy access to zip-compressed files.
•	Robust object-oriented design
•	Very low memory footprint as needed for consoles
•	Localization module - standalone, web-based localizer, enabling concurrent construction of localization information from remote places
•	Debugging support - includes tools for profiling and various runtime feedback mechanisms

Scripting

a flexible, object-oriented script that can be assigned to custom-programmed objects and thereby enable them to participate in the AI-state machine. The usage of scripts allows behavior to be changed at runtime. The language is event-driven and state-based.

Built-in Editors

•	Visual Scene Editor.
•	Visual scene player.
•	Plug-ins for 3DS MAX, Photoshop and ProTools (the plug-ins).
•	The basic workflow supported by the Glacier components consists of producing primitives in commercial geometry editor, texture editors and sound tools like 3DS MAX, Photoshop and Protools, building the scene from the primitives in the Editor application and playing the scene in the Player

Physics

Basic Physics, Collision Detection, Rigid Body, Vehicle Physics:

•	Advanced collision detection - precise at polygon level or a simpler level of detail if needed.
•	Advanced dynamics - real-time calculated cloth and hair on characters, plants, hanging bridges etc.
•	Rigid-body dynamics - makes possible realistic falling objects and rag-dolls

Lighting

Per-vertex, Per-pixel, Volumetric, Lightmapping:

•	Pre-rendered lights and shadows for detailed and realistic backgrounds.
•	Real-time lights (including volumetric light) - light sources illuminate objects as they pass by.

Shadows

Shadow Mapping, Shadow Volume:

•	Real-time shadows - as objects move their shadows change accordingly

Texturing

Basic, Multi-texturing, Bumpmapping, Mipmapping:

Shaders

Pixel, High Level:

Scene Management

General, LOD:

•	Advanced culling algorithms for optimal performance

Animation

Inverse Kinematics, Keyframe Animation, Skeletal Animation, Animation Blending:

•	Make realistic looking moving characters possible with and without any pre-stored animation.
•	Real-time inverse kinematics and animation blending - for lifelike movement.

Meshes

Mesh Loading, Skinning, Progressive:

Surfaces & Curves

Splines, Patches:

Special Effects

Environment Mapping, Lens Flares, Billboarding, Particle System, Depth of Field, Motion Blur, Sky, Water, Fire, Explosion, Decals, Fog, Mirror:

Terrain

Rendering, CLOD:

Networking System

Client-Server:

•	Multiplayer support - both split-screen and net-based.

Sound & Video

2D Sound, 3D Sound, Streaming Sound:

•	3D sound effects - includes occlusion, reverb/reflection effects through A3D/EAX APIs
•	Direct music support for interactive music - streaming sound is also supported.

Artificial Intelligence

Pathfinding, Decision Making, Finite State Machines, Scripted:

•	hierarchical 3D path planner supporting teleports and special moves (climb over wall, through hole etc.) as well as dynamic obstacles/appearing holes.

Rendering

Fixed-function, Render-to-Texture, Fonts, GUI:

•	Multiple cameras - for instance special cameras for zooming, sniper-scope effects as well as different strategies for a "virtual camera man".
•	Advanced 2D GUI API for user interfaces including common windowing controls. Uses 3D hardware for accelerated special effects.

they refused to give the license

Here it is written this is "commercial quality game engine" but when I was communicate with their sales people, they refused to give the license.

I can't understand what is the problem ?
