A life simulation game can revolve around "individuals and relationships, or it could be a simulation of an ecosystem".<ref name="fundamentals"/> == Definition == Life simulation games are about "maintaining and growing a manageable population of organisms",<ref name="ongamedesign"/> where players are given the power to control the lives of autonomous creatures or people.<ref name="fundamentals"/> Artificial life games are related to [[computer science]] research in [[artificial life]]. But "because they're intended for entertainment rather than research, commercial A-life games implement only a subset of what A-life research investigates."<ref name="ongamedesign"/> This broad genre includes [[god game]]s which focus on managing tribal worshipers, as well as [[digital pet|artificial pets]] that focus on one or several animals. It also includes genetic artificial life games, where players manages populations of creatures over several generations.<ref name="fundamentals"/> ==History== Artificial life games and life simulations find their origins in [[artificial life]] research, including ''[[Conway's Game of Life]]'' from 1970.<ref name="fundamentals"/> But one of the first commercially viable artificial life games was ''[[Little Computer People]]'' in 1985,<ref name="fundamentals"/> a [[Commodore 64]] game that allowed players to type requests to characters living in a virtual house. The game is cited as a little-known forerunner of virtual-life simulator games to follow.<ref>{{cite web | url =http://www.gamespot.com/gamespot/features/pc/unsung_heroes/sec2_02.html | title = Unsung Heroes: Little Computer People | publisher = GameSpot}}</ref><ref name="Computer Shopper">{{cite news | last=Kidd | first=Graham | title=Get A-Life | work=Computer Shopper | date=August 1996 }}</ref> One of the earliest [[dating sim]]s, ''[[Tenshitachi no gogo]]'',<ref name=Moby-Tenshi>{{MobyGames|id=/tenshitachi-no-gogo|name=Tenshitachi no Gogo}}</ref> was released for the 16-bit [[NEC PC-9801]] computer that same year,<ref name=GSpot-Tenshi>[http://uk.gamespot.com/pc98/adventure/tenshitachinogogo/index.html Tenshi-Tachi no Gogo], [[GameSpot]]</ref> though dating sim elements can be found in [[Sega]]'s earlier ''[[Girl's Garden]]'' in 1984.<ref name=AtariAge>[http://www.atariage.com/features/shows/cge2010_preview/pixelboy.html AtariAge at CGE2010], [[Atari Age]]</ref> In 1986, the early biological simulation game ''[[Bird Week]]'' was released. In the mid-1990s, as [[artificial intelligence]] programming improved, true AI virtual pets such as ''[[Petz]]'' and ''[[Tamagotchi]]'' began to appear. Around the same time, ''[[Creatures (artificial life program)|Creatures]]'' became "the first full-blown commercial entertainment application of Artificial Life and genetic algorithms".<ref>{{cite web |url=http://aaaipress.org/Papers/Symposia/Spring/1999/SS-99-02/SS99-02-017.pdf| title = AI Beyond Computer Games | author = Andrew Stern | year = 1999 | publisher = AAAI Technical Report }}</ref> By 2000, ''[[The Sims]]'' refined the formula seen in ''Little Computer People'' and became the most successful artificial life game created to date.<ref name="fundamentals" /> In 2008 also came the game ''[[Spore (2008 video game)]]'' in which you develop an alien species from the microbial tide pool into intergalactic gods. == Types == === Digital pets === {{main article|Digital pet}} Digital pets are a subgenre of artificial life game where players train, maintain, and watch a simulated animal.<ref name="fundamentals"/> The pets can be simulations of real animals, or fantasy pets.<ref name="ongamedesign">{{cite book|last=Rollings|first=Andrew|author2=Ernest Adams |title=Andrew Rollings and Ernest Adams on Game Design|publisher=New Riders Publishing|year=2003|location=|pages=477–487|url=http://safari.adobepress.com/1592730019/ch16|doi=|id=|isbn=1-59273-001-9}}</ref> Unlike genetic artificial life games that focus on larger populations of organisms, digital pet games usually allow players to interact with one or a few pets at once.<ref name="fundamentals"/> In contrast to artificial life games, digital pets do not usually reproduce or die,<ref name="ongamedesign"/> although there are exceptions where pets will run away if ignored or mistreated.<ref name="fundamentals"/> Digital pets are usually designed to be cute, and act out a range of emotions and behaviors that tell the player how to influence the pet.<ref name="fundamentals"/> "This quality of rich intelligence distinguishes artificial pets from other kinds of A-life, in which individuals have simple rules but the population as a whole develops [[emergence|emergent properties]]".<ref name="ongamedesign"/> Players are able to tease, groom, and teach the pet, and so they must be able to learn behaviors from the player.<ref name="fundamentals"/> However, these behaviors are typically "preprogrammed and are not truly emergent".<ref name="ongamedesign"/> Game designers try to sustain the player's attention by mixing common behaviors with more rare ones, so the player is motivated to keep playing until they see them.<ref name="fundamentals"/> Otherwise, these games often lack a victory condition or challenge, and can be classified as [[non-game|software toys]].<ref name="ongamedesign"/> Games such as ''[[Nintendogs]]'' have been implemented for the [[Nintendo DS]], although there are also simple electronic games that have been implemented on a keychain, such as ''[[Tamagotchi]]''.<ref name="fundamentals"/> There are also numerous online pet-raising/virtual pet games, such as [[Neopets]].{{Citation needed|date=May 2010}} Today online games which allow you to raise show dogs or [[sim horse game]]s are also quite popular. poooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooop === Biological simulations === Some artificial life games allow players to manage a population of creatures over several generations, and try to achieve goals for the population as a whole.<ref name="fundamentals"/> These games have been called genetic artificial life games,<ref name="fundamentals"/> or biological simulations.<ref>Ringo, Tad. 1993.

These include ''[[Wolf (video game)|Wolf]]'' and its sequel ''[[Lion (game)|Lion]]'', the similar ''[[WolfQuest]]'', and the more modest ''[[Odell Lake (computer game)|Odell]]'' educational series. In addition, a large number of games have loose biological or evolutionary themes but don't attempt to reflect closely the reality of either biology or evolution: these include, within the "[[God game]]" variety, ''[[Evolution: The Game of Intelligent Life]]'' and ''[[Spore (2008 video game)|Spore]]'', and within the arcade/RPG variety, a multitude of entertainment software products including ''[[Bird Week]]'', ''[[Eco (video game)|Eco]]'' and ''[[EVO: Search for Eden]]''. === Social simulation === {{main article|Social simulation game}} {{see also|Dating sim}} Social simulation games explore social interactions between multiple [[artificial life|artificial lives]].
