When you think of browser gaming, you might think of MiniClip; tiny flash games which were basically Angry Birds before, well, Angry Birds. But recently we've seen some amazing stuff using just browsers. Now you can run the shockingly gorgeous Epic Citadel in Firefox with just HTML5. Wow.
To try it for yourself you'll have to grab a nightly of Firefox (I tried it with the current stable release of Chrome and it didn't work), then hit the HTML5 version of Epic Citadel. Yes, it's just a demo, but it's a full-on expansive test of the Unreal Engine 3, which means we could soon have all sorts of amazing games just in your browser, and that really would be something.
