Please answer the following question: Information:  - Jeffrey Tunnell is a computer game producer, programmer and designer.  - A flight simulator is a device that artificially re-creates aircraft flight and the environment in which it flies, for pilot training, design, or other purposes. It includes replicating the equations that govern how aircraft fly, how they react to applications of flight controls, the effects of other aircraft systems, and how the aircraft reacts to external factors such as air density, turbulence, wind shear, cloud, precipitation, etc. Flight simulation is used for a variety of reasons, including flight training (mainly of pilots), the design and development of the aircraft itself, and research into aircraft characteristics and control handling qualities.  - The user interface (UI), in the industrial design field of humancomputer interaction, is the space where interactions between humans and machines occur. The goal of this interaction is to allow effective operation and control of the machine from the human end, whilst the machine simultaneously feeds back information that aids the operators' decision-making process. Examples of this broad concept of user interfaces include the interactive aspects of computer operating systems, hand tools, heavy machinery operator controls, and process controls. The design considerations applicable when creating user interfaces are related to or involve such disciplines as ergonomics and psychology.  - Betrayal at Krondor is a DOS-based role-playing video game developed by Dynamix and published by Sierra On-Line in the summer of 1993.

She is married to Ken Williams and retired from her career in 1999. Roberta Williams is one of the most influential PC game designers of the 1980s and 1990s, and has been credited with creating the graphic adventure genre.  - A-10 Tank Killer is a flight simulation computer game for Amiga and DOS platforms developed and published by Dynamix.

Even art games, games purposely designed to be a work of creative expression, have been challenged as works of art by some critics.  - A video game is an electronic game that involves human or animal interaction with a user interface to generate visual feedback on a video device such as a TV screen or computer monitor. The word "video" in "video game" traditionally referred to a raster display device, but as of the 2000s, it implies any type of display device that can produce two- or three-dimensional images.

It was launched March 25, 2000 by a Delta II rocket from Vandenberg AFB and ceased operations in December 2005.  - An electronic game is a game that employs electronics to create an interactive system with which a player can play. Video game is the most common form today, and for this reason the terms are often mistakenly used synonymously. Other common forms of electronic game include such products as handheld electronic games, standalone systems (e.g. pinball, slot machines, or electro-mechanical arcade games), and exclusively non-visual products (e.g. audio games).  - Aces of the Pacific is a combat flight simulator game developed by Dynamix and published by Sierra Entertainment in 1992.

Its success caused Dynamix to create a very similar follow-up "Aces Over Europe" in 1993.    Given the paragraphs above, decide what entity has the relation 'genre' with 'combat flight simulator'.
