I've installed this excellent theme on several sites, across different genres - NONE of them anything to do with gaming.
I was attracted by the theme's look and feel - bold and colourful, and I've used different colours on various sites.
The site I've (arguably) done the most with is an electronic music site - http://www.nervejam.com. On this one, I've edited the sidebar widget to remove the word "game" so it now says Reviews, not Game Reviews. I've also moved a couple of posts from the general (news) class to the "video" class, so they appear as videos in the sidebar widget - excellent, and very elegant.
I've also used GamePress on my Gambling blogging site - http://www.bashthebookies.net, this time using the "green" colourscheme. Again, it looks amazing, and now I've worked out how to edit the widget, I'll be adding "reviews" of tipping services etc..
I've been using WordPress themes for years, but there's always "something" not quite right.. Not in this case - GamePress ticks all the boxes.
