Every monday he does a little post on patreon to talk about random things and about the state of the game. The last few weeks he was telling that the game can be played from start to finish, finished with all the main events, he is just testing and replaying and filling in the gaps. I was hopeful, then this week, he comes and says that testing is done but want to redo a part of the game to feel more immersive etc. I genuinely have no idea at this point if the game is 95% done or sitting around 55%...well estimations are from this year to this decade.
