本文一方面介紹本期專題論壇的宗旨，另方面彙整五名線上遊戲學者專家在圓桌會談的意見交流結果。這些討論結果主要可歸納成以下三個面向：首先，線上遊戲的媒體獨特性，影響其研究執行與實踐的方法；第二，遊戲暴力的意義體系，應置入文本、玩家經驗與社會情境的意義脈絡；以及第三，線上遊戲是現實危險社會的濃縮版本，而網路中介屏障提供玩家賦權的可能。本文最後呼籲後續研究者拓展線上遊戲研究領域與理論視野。 This article started with an introduction of the objectives of planning and holding the special forum on online games and media culture. It went on further to synthesize more discussions from the face-to-face roundtable meeting among the five invited experts in this field. The discussions generally focused on three aspects. The first aspect is to look at the research methods and the related communication theories as well as the unique characteristics of the online games. The second aspect is to explore the significance of game violence which has been explained in the network of game texts, gamer experiences, and social contexts. The last aspect is to focus on the safety issues of online games, in which the gamers practice and cultivate their competences to deal with the risks in the real world. The article ended with suggestions for expansion and extension of future research efforts as well as the theoretical scope.
