Have you already spotted the 'Google Plus Games' on your account?
If not, login to your account and look for "Games icon" on the profile menu.

Just like Facebook, each Game App requires permission to get some of your profile data, friends list and get privilege to post your Games scores on Google+ stream.

Do you think more games should be introduced? If yes, which ones?
If not, I agree with you, why is Google duplicating everything that already exists.
