It's been a while but it seemed like Ryo, after getting his rear handed to him and having his father die at the hands of the same foe, knew he couldn't go and kick ass and take names. He had a calm head on his shoulders and had to do his obe-track-minded detective search. Since Shenmue was supposed to have many "episodes", I wonder if this more slow approach wasn't far off from a "Kung Fu" (TV series) where Ryo walks his native and foreign lands, learning and helping others on his quest?
And then asks everyone if they are, or know or have seen sailors. Or the 5 (or however many) Blades. Or if they saw a car the night when the rain turned to snow....
I did enjoy seeing if Sega put a limit on how many sodas Ryo could drink. Alas he didnt politely decline nor did his bladder burst at about 20 drinks in one sitting. Incredible control over his body.
