Star Citizen is a space simulation game in a large and persistent simulated universe.

Quantum is a system for simulating activity with economic impacts and determines how much of raw material or assembled products are available and where, how much things cost, how busy and how dangerous or safe space travel lanes are, and other such aspects of economic scaling.

Subsumption AI is used to drive NPC behavior up close. The game is supposed to have a population that is 90% AI NPCs that drive economic variation and action in general. This makes the game world seem alive even if there are no players currently with you in game. The NPCs have the ability to decide what to do, how to move around, make jokes and idle banter, and can use various equipment in the game as well as fight either in person or as spaceship pilots.

Not totally sure about pCache but it appears to be used on the server to capture changes to state in the universe that should be stored persistently. This is part of the server container streaming feature which allows servers to stream in areas and sets of objects as players approach and then stream them out when they are left empty for a time.
