Nice find. They do seem to have better sales, overall, with the GameCube versus the PS2. But that said, there are some criminally undersold games on each system. 6,843,779 per 28 titles (244,421:1) on the Cube and 6,890,662 per 44 titles (156,606:1) on the PS2
And Xbox sales are complete scheisse across the board. If Sega 'fans' really did go to Xbox, just to ignore the games, I don't think Sega ever had fans (or they became extremely resentful). 3,516,972 per 35 titles (100,485:1).
