I'm a bit out of the loop, but my Mac Software update client says Blender Player has been discontinued. The current (last?) version of Blender Player is 2.79, file build date 9/14/2017.
I'm wondering what the story is behind this? I looked through the release notes going back to V 2.73 on the official Blender website and did a search via DuckDuckGo (my preferred search engine) and did not find any mention about what's going on with the Blender Player, and I looked deep clicking on "read more" on closely related topics on version 2.79 and 2.78.
