Shenmue 1 runs are super long, and now that there's a PC version, finding glitches should be faster/easier. Where are all the really bad places in the run that really need workarounds? Things that need skipping? I'd be up for glitch hunting.

Anyone will tell you the work week sections are the ones to be skipped. Thing is - finding a glitch is going to be tough. Those sections are very heavy with the handholding, and the event triggers that would need to be reached in order to skip them are mostly tied to the ingame clock, which you can't skip on Shen 1 like you can in 2.

Good luck though!
