This is a promo we'd love to see in our region. Sony Computer Entertainment Asia is giving away HK$10 (about $1.30) in PlayStation Network credit to those that are able to find a "mysterious avatar" in Sony's virtual world. Clues can be found on posters in the service.
The money certainly isn't enough to buy anything significant, but it is enough to buy a trinket from the PlayStation Home's in-world store. Participate in a game and win free virtual pants? We like the sound of that. Hopefully, SCEA or SCEE will do something similar in the future.
