Thanks for the heads-up! This is not the first, and will not be the last digital version of a game to be removed so always insist on a playable (right out of the box), physical version whenever possible or look for legal DRM-free versions whenever possible. Many game storefronts, publishers and developers do not share the same vision and views as game collectors and preservationists, so when things like this happen, games could potentially disappear into the void forever. Even mobile titles released on iOS and the Google Play Store are not immune to this, which is quite unfortunate as titles on those platforms are normally digital only. For a classic example of this problem, look no further that P.T, a game by Kojima Productions released on the Playstation Network for a very brief period of time only.
