Did you know that there are several special conversations you can have in the tiny amount of time you have after Ryo is fired from his job and before you meet Tom to learn the Tornado kick? You only have a short window of FREE play before the game forces you to meet Tom, so the only way to see them all is to save the night before and keep reloading your game to go to a different person each time. It's been a long time, so my memory is fuzzy, but I seem to recall:
-Nozomi thanking Ryo for her rescue from the Mad Angels, and Ryo promising to take her out on another motorcycle ride!
-Lapis Fortune Teller foreshadowing Ryo's journey to China, with an image of Shen Hua appearing in the crystal ball.
-You have BARELY enough time to get all the way back home from the harbor to have one last conversation with Ine-San where Ryo comes clean about his intentions to go after Lan Di and promises that he won't die.
There may have been more, since it is the last time you can wander freely in Shenmue I. But I just remember being so amazed that they bothered to put these conversations in seeing as you have to go so far out of your way to trigger them!
