To help sell you on Ratchet and Clank Future: A Crack in Time
(which hits stores next week) the folks at Sony are releasing the first of two demos for the game this Thursday. If you listen to the Full Moon Podcast (which you should as it's one of the better gaming podcasts on the market) you already know that they are releasing two full demos for the game, one which will allow you to check out the Ratchet gameplay while the other will allow you to play the Clank gameplay. The demo on Friday will allow you to check out the Clank side of the game which means you'll get to play around with the time manipulation part of the game.
I'm pretty stoked about the game as the folks at Insomniac are finally going to complete the trilogy. They've been hinting at some major changes in the series at the end of the game and I'm interested to see where they take things.
