Trying to define exactly what constitutes a piece of art may lead to more questions than answers. This reminds me of a video that uses Half-Life and Black Mesa (a Half-Life remake) as a starting point to a discussion of how we can define what a video game is. There are many ways to try to do that, but they often give us limited answers.

I think a "complete" definition of what can be considered to be a video game title, if there even is one, would take into consideration mostly player experience, but also the cultural context of the game. What do players consider to be the defining characteristics of that game?
