Burnout Paradise: The Ultimate Box will be arriving on the PC in February 2009 and will be coming with an amazing demo. The whole game will be playable in a trial period, while the extent of the trial period has not been confirmed yet, it is most certainly a great way to get people to check out the game. This sentence from the Criterion news post really strikes a cord with me;
Moreover, this will not just be a single-player demo, it will include the multiplayer component of the game, Freeburn which will let you compete in challenges with up to 8-players in all. Finally the demo will come with the Burnout Store, which along with a whole load of wonderful stuff will allow you to easily upgrade to the full game.
