Great Scott! There are far too many deals on Steam to get through today, but in my opinion this one's the most exciting. Now you can get all of the Back To The Future episodes for £8.48, that's about £1.70 an episode, but more importantly it'll make you a saving of almost £7.50 on the next best offer coming in from Direct2Drive. If you do end up buying the game you'll get to join Marty and Doc Brown on another adventure through time, which should be irresistible to any fans of the films out there.
