As people have said FotU does add a couple of new modules that will alter the difficulty and add a little bit more complexity and overhead (but very minimal). At the moment I don't believe anyone has played all the episodes in season 3 (except the play testers) so we don't have much information on the quality of the content in season 3 where as Season 1 is tried and tested.But as everyone has said the game is modular and everything is compatible, if you like this game you'll eventually want to pick up every season and season 1 is a good place to start
