Seems like every major Japanese publisher has a free to play game for PlayStation Network. Square Enix ported Million Arthur, Tecmo Koei’s Dead or Alive 5 Ultimate Core Pack is a freemium fighting game, Sega has Samurai & Dragons, and Capcom has Dragon’s Dogma Quest.
And Konami? They just announced Power Pros Stadium in this week’s Japanese magazine round up. Power Pros is a long running baseball series with super deformed characters and at one time 2K Games localized Power Pros games for North America. Power Pros Stadium is an online baseball card game and it will be distributed as a free download for PlayStation 3 and PlayStation Vita.
