Apps (games or not) can still interact with Hangouts via the Hangouts API, which is not affected by G+ Games shutting down.

Aside from embedding the game in the G+ Web UI, what are you missing that you would have had with G+ Games with existing G+ APIs (Hangouts, Moments) and the Google Play Game Services API?
AFAICT, shutting down G+ Games just means that the Google+ UI as a portal to web games is going away.
