All this is from vgchartz, so if you want more details on other stuff, head there.
So, I'm sure some of you have been wondering how some of the recent software has been selling. In my opinion, the past month has had more quality game releases than there were for - basically - it's entire first year. And now the numbers (first week; second week):
Guitar Hero III - 271,053; 98,121 (~370k)
Manhunt 2 - 51,371; 23,168 (~75k)
Mario & Sonic - 81,445
Fire Emblem - 66,711
Lego Star Wars - 37,119
If anyone is curious, GHIII for the 360 broke the 1 million sold mark.
