To me the ability to create your own tournaments (for now only in custom mode, but will be added in a patch to the other modes too) and the ability to add leagues to an existing custom save are two things I am looking forward to. In general I think everything that adds more customization to the game is good.
However, I also share some of the concerns made by Colorado and I have some doubts regarding the new financial and ingame features.
Nevertheless, I will for sure buy the game to support further development and already know that I will once again spend way too much time playing it
