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 academy's annual 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." 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 Dwarf Fortress, developed by Bay 12 Games and published by Kitfox Games. History 
Initially the Interactive Achievement Awards had separate awards for Computer Strategy Game of the Year and Computer Simulation Game of the Year. These would be simplified to just Strategy Game of the Year and Simulation Game of the Year in 2005. 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)
