Traditionally in adventure game engines, non-player characters were static awaiting the player to interact with them to trigger an event. However, Virtual Theatre allowed non-player characters to traverse the world in seemingly random patterns, interacting with their environment. Upon the engine's first release, it rivaled competing engines such as LucasArts' SCUMM engine, and Sierra's Creative Interpreter, due to its then high level of artificial intelligence.
Another advantage of the engine is that it is a cross-platform engine. It was also faster on the Amiga than the C code that was used by many USA programmers at that time. Compared to the Sierra titles, the engine became in this respect more sophisticated, a reason why Revolution did the conversion of King's Quest VI to the Amiga.
All of the in-game objects (including non-player characters) in Virtual Theatre occupied space, which was a unique feature for an engine at the time. Consequently non-player characters had to side-step the player's protogonist and any other object they came across, as well as the player had to side step them. When a non-player character bypassed the protagonist, he or she uttered a comment (like "Excuse me, Sir"). As the result, the engine achieved a more realistic game world than previous engines were able to provide, though non-player characters could unwittingly block a path as the player was traversing the game scene. This was remedied with the release of Broken Sword: The Shadow of the Templars, where the protagonist, if found his way blocked by another character, could simply walk through him.
Games that use the Virtual Theatre engine can be now played on modern hardware using ScummVM. Consequently the games using the engine may run on the platforms the titles were not officially released on.

Famous quotes containing the word features:
“All visible objects, man, are but as pasteboard masks. But in each event—in the living act, the undoubted deed—there, some unknown but still reasoning thing puts forth the mouldings of its features from behind the unreasoning mask. If man will strike, strike through the mask!”
—Herman Melville (1819–1891)
“The features of our face are hardly more than gestures which force of habit made permanent. Nature, like the destruction of Pompeii, like the metamorphosis of a nymph into a tree, has arrested us in an accustomed movement.”
—Marcel Proust (1871–1922)
“Each reader discovers for himself that, with respect to the simpler features of nature, succeeding poets have done little else than copy his similes.”
—Henry David Thoreau (1817–1862)
