PlayMG Corp., San Diego makers of a gaming device aimed at youngsters, and BillMyParents Inc., the company that provides prepaid cards that track spending of same youngsters, announced that each new MG will use the payment service.

MG, which stands for more game, said it’s the first dedicated Wi-Fi gaming system for the Android free app games market, targeting 63 million kids under age 18. Some 39 million members of that target market do not own smartphones, PlayMG said.

Because the MG doesn’t require expensive data plans or packaged games, it’s much cheaper than letting kids use tablets or smartphones to play their games, the company said. Instead, the MG relies on downloadable free games from a market of some 60,000 free applications, the business said.

But nothing is really free in this space and inevitably, gamers will be spending some money, which is where BillMyParents comes in.

Through a reloadable, prepaid MasterCard, young ones can enjoy the games they want, while staying within set spending limits defined by parents, the companies said.

The MG, which carries a suggested retail price of $169, is being rolled out for this year’s holiday shopping season, but the first 2,000 adopters who “pledge” $99 via Kickstarter will receive one. A pledge for a different amount will get a $20 discount, the business said.

PlayMG Corp. said it’s in talks with some major retailers and will be announcing partnerships as these are made.
