According to Famitsu, Genki is to release an add-on pack for its Wiiware title LONPOS for the rather hefty price of 500 points (the game itself is 1000 points), and Namco wish to include downloadable content for their Wiiware game Mojipittan.
What a rip-off! I wanted the Wii to become more like Xbox Live, but not like this. I consider microtransactions to be the biggest rip-off in the video game industry, especially in cases like this when the developer deliberately releases the game incomplete so you have to pay more to play the full game. And the fact that it's for Wiiware, which is already downloadable content itself, makes it even worse.
