IMHO, I don't think you should come up with a design just because another site uses it, especially that site has a totally different nature from yours. Take Stack Overflow for example, the white background is geared for readability. But at the same time, it's minimalist and cold. This may not be suitable for your gaming site.
What you want to do before you even design, is to define "the feeling" visitors should have when they come to your site. If it's a gaming site, it's supposed to be more visually engaging(but not overwhelming). You may use different illustration, icon styles.
Having that said, i find that one trick to get around using only all white, but still keeping that airy 'n open feeling is, to have your content area #fff, but pick a very faint gray as site's background color. eg: f8f8f8. the subtle difference in color creates a visual cue for division of plane, very subtle.
