The first one originally slipped by my radar on its release. The second, I was given a preview link for that episode alone. It was a useful experience, I think, actually, as I imagine a (perhaps small) percentage of gamers might purchase episode two because the title interests them without having even heard of the first in the series or with any inclination to fork out additional money for it.
The initial, wobbling "?" above my daft head did not adversely affect the game's grade in any way.
