If you're on the fence about Dead Rising 2 (read our Busy Gamer Review, it's a mixed bag), now you can try before you buy right in your Web browser. You will need Java installed and, once you pass the age gate, you'll have 30 minutes to play it full screen or in the browser window. Free up your mouse from controlling the game by pressing Shift-Esc if, say, you want to blog about it or run screaming.
If you like what you see, there's a convenient link to download the full game right away from the official Capcom store for $30 (same price as Steam at this writing).
Other games on the Gaikai demo showcase include Crysis 2, Dead Space 2, Dragon Age II, Mass Effect 2, The Witcher 2 and Farming Simulator 2011.
No, really, you can check it out...
I like the concept.
