Here is a life tip you spell does as d-o-e-s.
it becomes free to play after a period of time. I haven't seen any mention of making the game pateron subscription only. yes you have to redownload it everytime. its recommended not to use any previous saves after redownloading, however this most recent update has 0 story content so it doesn't matter as you can see 90% of the new content from the main menu. lol
