In the past few years, there’s been quite a few Free 2 Play games on the Nintendo 3DS, such as Pokémon Shuffle and Denpa Ningen no RPG Free!, (with over 4 million downloads and over 2.2 million downloads respectively). But not all of them have been so successful… far from it. For example, SEGA pulled the plug on its Initial D Free 2 Play game back in June.
As for Kaku-San-Sei Million Arthur, it’s far less successful than Pokémon Shuffle and Denpa Ningen no RPG Free!, but still profitable enough for Square-Enix it seems. Last week, they announced that the game had been downloaded over 500 000 times. The company even launched a special campaign, where users can win a rubber strap (500 people) and even a body pillow (10 people). More details on this page (Japan-only).
