D.I.C.E. Award for Strategy/Simulation Game of the Year

The D.I.C.E. Award for Strategy/Simulation Game of the Year is an award presented annually by the Academy of Interactive Arts & Sciences during the D.I.C.E. Awards. This award recognizes games "in which user directs or manipulates resources to create a set of conditions that result in success as determined within the confines of the game. These games can offer the user the chance to simulate or to virtually reproduce an experience, real or imaginary, which would require some form of equipment. Strategy games emphasize the planning of tactics rather than the execution". All active creative/technical, business, and affiliate members of the Academy are qualified to vote for this category. Originally, there were separate awards for strategy games and simulation games, which simulate aspects of the real world.

The award's most recent winner is Dune: Spice Wars, developed and published by Shiro Games and co-published with Funcom.

History
Initially the Interactive Achievement Awards had separate awards for Computer Strategy Game of the Year and Computer Simulation Game of the Year. The categories would then be merged into Strategy/Simulation Game of the Year in 2008.
 * Computer Strategy Game of the Year (1998—2004)
 * Computer Simulation Game of the Year (1998—2004)
 * Strategy Game of the Year (2005—2007)
 * Simulation Game of the Year (2005—2007)
 * Strategy/Simulation Game of the Year (2008—present)

There was a tie between Age of Empires and StarCraft for Computer Strategy Game of the Year at the 1st Annual Interactive Achievement Awards.
