Gameplay is the most important factor to me, but it doesn't have to be the driving force of the game. I like a game whether it's heavy on story or not, but I want the interactivity to be enjoyable. I like Nintendo because they are doing what no-one else is. They are trying to make gameplay as immersive as possible. But I still like regular controls, too. Basically, the interactivity in the game needs to be good and interesting even if the mechanics themselves are simple.

I like a game with an ending. So I generally don't like arcade-style games.

I don't need good graphics. As long as I can distinguish between an enemy and a bush, I'm fine. But I won't say no to a graphical upgrade if I think it looks good. Having good music helps. I love music, but I'm picky so I need it to not annoy me.
