I wonder if a process of elimination can help.
I tried to thin out at least what seemed exclusive to S3 by tiers. Sometimes it's hard to remember if it's actually new, or just if you forget it (esp. all those shops in S2).
I figure it’d easier if some other ears can listen through some of these and make sure some weren’t in S1/2, and then we can weed out the Shenmue Online from the properly new. Maybe some of us could first weed out the unlikely's and maybes?
I left out those which I'm assured are reused (incl. SO and S2 unused), but one's always open to correction (lest we offend Wude).
