There are certain subjects that one expects to discuss in the rarefied echelon of game production. Player models. Weapons. Particle effects and complex shaders. Lofty, technical, intricate issues – humble props would not normally be featured in such glorified company.
However, as it happens, props are probably the single most important element of any level. Sure, each Nuclear Dawn stage is loaded with effects, scripts, particles and animations – but underneath it all, supporting the illusions of prettiness, are good old props.
In game-making terms, just as in movies, a prop is a supporting model: the lonely table in the corner of the room, the broken-down vehicle just out of your sight, the humble empty bottle of water on the floor. A few well designed and expertly conceived props can make or break the sense of immersion and realism of any scene or level.
