Free-to-play MMO publisher OGPlanet has announced that their in-game currency is now available for publish in the form of pre-paid game cards, available exclusively at Blockbuster stores.

The virtual currency, called Astros, can be purchased online, but the new agreement with Blockbuster marks the first time OGPlanet-specific game cards will be available at a "brick-and-mortar" retail outlet.

Astros can be used in OGPlanet's four titles -- Albatross18, Rumble Fighter, Cabal Online, and the upcoming La Tale.

"The availability of OGPlanet game cards at Blockbuster stores nationwide represents an entirely new level of accessibility for OGPlanet fans," said Don Choi, COO of OGPlanet. "We're thrilled to be working with Blockbuster in this venture. Their success as an entertainment retailer makes them an ideal location for distribution of OGPlanet game cards."
