One of the most hyped games for the Nintendo Wii only sold 130K for the first day in Japan. The biggest issue was that there were hardly any lines for gaming stores. Usually, a game will have long lines awaiting the newest hot release. However, 130k is a respectable number by all means.
It's only he first day and Mario games have been known to keep selling throughout the lifespan of the video game. Games like New Super Mario Bros sold 900,000 during the first week, so Super Mario Galaxy still has agood chance to catch up.
We'll see if people buy it up or not.
