I guess we all know about the old homeless man at the Freestay Lodge and the question about rivers that he asks.
But did you know that there is not just one but two more instances where he will ask Ryo a question that triggers the action selector?
I totaly stumbled across the first one recently and was pleaseantly surprise to find something new yet again.
Of course this sparked my interest in finding more and I dug through the files and found one more conversation.
Typicaly for Shenmue, for everything that you stumble across you'll have trouble figureing further things out.
It took time and different attempts until I got him to talk for the third one. That bum was always sleeping.
The solution was to make no progress at all and come back the next day. Too simple I guess...
Shenmue is like life. You always get something new to learn.
