Google Playground is a destination, currently, with no monetization. So any gamedev effort and ideas we contribute into it are collected by Google.
EDIT:
It is offered as "for funsies with your pals in America, bros!" and it looks a lot like it's almost a feature in the Google Play portfolio which makes me think this wasn't thought through fully.
So Google doing something strategic here which is not clear to me.
- are they training their AI?
- are they collecting user feedback for an eventual commercial launch?
- are they building hype?
Why did Google spend the money on this?
