There were already crypto app/games with NFTs on google play store before this announce AFAIK. But apps that can make users wager, I think is more appealing to users that could lead to adoption. They still are suppressing this kind of apps so, there might just be no effect at all after this announcement.

But those casino apps, may get around of this kind of policy. The Utopia project does have a poker game in their app, they may be able to update their app now for playing casino games to be available.
