Unity made the process of importing textures so simple I found myself tweaking them in Photoshop all of the way through production. Being able to see the resulting changes instantly reflected in the scene speeds the production enormously.

Integrated Editor
Keyframe animation system with an easy to use interface that allows you to animate almost all game object parameters
Drag'n'drop to set values and hook up everythign from game logic to graphical effects
Play button for instantly trying out your work, and pause and step-frame to try out the game as you go
Game flow of arbitrarily sized games can be created, tested and tuned in the editor [NEW]
High performance automated asset pipeline. Never think about importing your assets again. Save your .psd file in Photoshop and see it update live in Unity without clicking a single button
Customizable pane layout system. Allowing you to customize your work environment as you see fit

Extendible render-to-texture effects, including glow [Unity Pro feature]
Spotlights, omni-lights and directional ligths, as well as projected textures, halos and volumetric light cones
Support for latest graphics card features such as bumpmapping, reflection mapping, refraction, cubemaps, trilinear filtering and mipmapping
Unity comes with an extensive library of 32 shaders including Vertex Lit, Diffuse, Glossy, Bumped, Bumped Specular, Reflective, Self-illuminating, a Toon (Cell) shader, and 9 different particle shaders
Advanced shaders automatically fall back to simpler versions on old graphics hardware
Low level socket libraries can be used for advanced networking
Audio
3D positional audio with distance attenuation
Support for nearly all audio file formats
Game Structure
Component based modelling of game entities. Components can be added and removed while the game is running
Powerful (and fast) query and messaging system for communication between components
Support for switching between scenes, data that survives across scenes, and saving game settings and status
Import File Formats
Import models, animations and animated characters from all major 3D applications such as Maya, Cinema 4D, Lightwave, MotionBuilder and Cheetah3D. Supported file formats are: .fbx, Maya .mb files, .3ds and .blender. With the .3ds format virtually every 3D modelling application can be used with Unity
Imports all major image and movie formats using QuickTime. Save your Photoshop files complete with layers and let Unity automatically compress your images with Unity's high quality S3TC texture compressor. All automatic without even pressing a button
Automatic heightmap to normalmap conversion
Different mipmap generation methods (detail fade, Kaiser filters, gamma corrected, and others)
