Famitsu Software Stuff
Things have slowed down a lot, nothing new is huge, no major borders passed... really not much of note this week.
Recently some supplementary 2008 data has come from Famitsu, though, including some updates on budget games. This is as good an excuse as any to show off one of my favorite charts that result from this new data.
In April, all four Gyakuten Saiban/Ace Attorney games were rereleased. In the case of the latest game this was only its second release, but the others have already come and gone multiple times on both GBA and DS. And they still go strong! These four releases combined to sell a third of a million copies in 2008. The series isn't exactly Monster Hunter, but it's definitely one of Capcom's success stories of the last decade.
