Playphone's "Game Portal" will be completely separate from the Google Play Store. Playphone claims this is a good idea because the store will offer direct carrier billing with Verizon. Of course, the Google Play Store offers the same thing, so we're not sure how it will benefit users to have a separate game store. Playphone is also saying that Verizon's "massive distribution network and marketing muscle" will be good for game developers. We can't argue that, but it still doesn't give a reason why users would want to split their money between this store and Google Play.
Still, Android does need a gaming social network similar to Apple's Game Center, and this may be the best option, because none of the current options like Scoreloop or Swarm only get visibility through the games that are connected. Verizon has big marketing muscles. And, the carrier loves to bloat add value to its devices.
