I played them in the alphabetical order that Windows puts it in.
5 Days a Stranger, 6 Days a Sacrifice, 7 Days a Skeptic, Trilby's Notes.
I don't care if a story seems weird, because when I first got the VGA version of Quest for Glory 2 I had no idea what happened before then, but I managed to figure some things out. There was a hermit in the first game that dropped his H's, there was an ogress named Baba Yaga, there was a wizard named Erasmus, and the town was called Spielburg.
