Personally I'm not much of a gamer so I tend to be interested in narrative stuff, abstract visuasation and geometry stuff or just exploring interesting environments.
And the games I do like tend to have one or more of the above qualities.
You might be an RPG fan, a strategy gamer, an art aficionado , looking for productivity or educational tools or any number of things.
