We've released a fully functional partial season demo. You can download that demo
here. The demo will allow you to play out from the start of the career through the summer recruiting and through the regular season of one year and does not expire. If you wish to upgrade from the demo to the full version simply go to the webstore and purchase the game and then all you need to download is the 1.01 patch, enter the code the first time you run it and you will be all set. You will be able to continue your save game from the demo if you wish.
