the 1and 2 are parts when you play 2 it starts following events releated to 1 and it is possible to play 2 whitout 1 i would not recomend it do if you dont play 1 you start whit predetermant stats that are a lot worse than if you just play 1
Something got to my head, wonder if the old free version is complete or not?, or are they keeping the new version with new arts and stuff for paid?, because if the content is not finished in free, i won't support it
in the free version of the games you can play until day 47 while in the paid version it get to day 69 where somthing happens that put you in a coma which you wake up from at the start of part 2 ps also i have seen people commet that you can find the game free on some platforms
