Who is that hooded Arthur? I mean, that Arthur in the hood? I mean, that Arthur named Arthur?
Whatever. It's a mystery. It will never be solved.
This opening doesn't exactly match the plot of any game I'm aware of, but it is basically a mix of the first two Fable games.
By which I mean the total sum of all three panels doesn't match the opening to one specific game. That first panel is probably the opening to about ten thousand video games, movies, books, TV shows, radio plays, and limericks.
