Behold the power of WoW Insider -- GotGame told us about their browser and social networking service a little while ago, and we were so much more fascinated with the browser part of their app that they split it off. And here it is: Rogue is what they're calling their ingame browser application -- you can download it for free from the site, and after a quick install, you can open up a browser in any PC game.
As lots of commenters said on our last post, this isn't really an ingame browser, it's more of an overlay that lets you browse while playing the game. And all it really does is save you the couple of minutes it would take to tab out and check your own browser (or just run WoW in a windowed mode, and use both at the same time).
But there are a probably a few users out there who would find it really useful. Downtime is the main issue I can think of (though lots of my downtime is filled lately with the Bejeweled addon anyway). But if you've been waiting for a solid, standalone ingame browser to come along (complete with Flash support, which makes it easy to pull up Hulu or Pandora while playing), Rogue is it.
