Ah I remember the shopkeeper of Monkey Island, he wasn't moving like you (if you follow picking his path he would be super slow, if you enter/exit he will teleport in the shop) but him and the cook moved even without player input (they could exit from their room) so they had a mini schedule. But click and point games and even rpg had fixed character that wouldn't move without player intervention, the schedule become popular with Gothic and then with Oblivion.
There was an adventure with rpg elements game of 1991 "The adventures of Robin Hood" made by Millennium that was an entire open world with schedule for each character that were different each season...the world will keep going with or without your intervention: the sheriff will hang people, beggars will appear but you could save those people with your merry men or just being a spectator....you could even spy women going naked in the lake.
