Games where the world responds vividly to your actions and almost any problem can be solved in multiple ways: sneaking in, negotiating, hacking, finding a way around, or breaking through. The game's systems work together, and the player comes up with the solutions themselves. The benchmarks of this genre include Deus Ex, Dishonored, and Prey.
This is the historical name for the genre: games "simulate" a living world with systems that work together — security, electricity, fire, and physics. This has nothing to do with driving simulators.
Where to start getting acquainted with the genre?Dishonored or Prey are easier for a newcomer to understand. Classics like Deus Ex and System Shock are best enjoyed in updated versions.
