電玩迷人之處，在於藉由遊戲過程中，玩家拋開生活現實，扮演遊戲人物體驗奇幻經歷。然而在一些相對小眾遊戲裡，玩家所扮演的，有時卻是下流的電車色狼、癡漢乃至於暴力性侵者。這類以情色內容為主的成人電玩遊戲雖看似小眾，惟殊不知在網路普及前，這類主要以家用電腦（PC）為平臺的遊戲即長久流傳於臺灣社會裡，迄今交易依舊不絕。 2009 年我國曾發生模擬性侵遊戲《Rapelay》取締事件，該事件甚至驚動監察院提出糾正案。這類型的凌辱系電玩遊戲雖在臺灣流通已久，但躍上公共輿論探討甚至有人因此遭受刑事裁罰，本事件雖屬首例，但相信無人能擔保此類涉及性虐待、性暴力的成人軟體遊戲的流通散佈從此就在臺灣銷聲匿跡，相關的法律課題仍容有探討之餘地。有鑑於此，本文爰以我國 2009 年《Rapelay》取締事件為中心，就此類成人電玩所涉及相關法課題，展開鳥瞰式的探討。

RapeLay is a 3D eroge video game made by Illusion, released on April 21, 2006 in Japan. The game centers on a male character who stalks and rapes a mother and her two daughters. Despite not being officially distributed nor supported outside of Japan,three years after its initial release, the game garnered both domestic and international attention and controversy for its content. In Apri, 2009, The Garden of Hope Foundationfound the rape games purchasable on tw.yahoo.com and ruten.com.tw and claimed such video game needs to be more strictly banned. The Control Yuanalso issued a correctionto The Ministry of the Interior, Ministry of Economic Affairs and National Communications Commissionin October, 2009. Despite all those efforts, sexual violence video games still easy to buy in Taiwan and related legal problems seem not to being much-discussed. In this essay, I will discuss several important legal issues on sexual violence video games.
