I'm still trying my best to keep a lid on things. Preoccupy myself as best I can with anything but Shenmue, and put it to the back of my mind. I recon get Christmas out of the way, and get to early 2019 before pulling the trigger and getting excited. Otherwise the wait just gets harder and longer. In terms of games, I have cut Shenmue down to 2 hours a week on stream and that's it. I have deliberately switched off, and trying to play other games like Black Ops 4 and Spiderman, as well as have to play Horizon Zero Dawn (still haven't opened it), as well as buy Red Dead Redemption 2.
I am also in the camp of, "please don't show anything at all". I know the thirst gets worse by the day for most people, but the less they show the better. We live in the age where you don't need to go to the cinema to watch a movie, you can just piece together the 4 trailers you have seen for it, and get the jist. Same with TV shows. The less we see from Shenmue 3 the better, and I don't want to see Baisha at all until I play the game.
