I thought it would be interesting to see what the ratios for pre-orders vs first week worldwide sales would be. This way we can look at past titles on each system and have a better idea of what future titles may do in their first week.
Every week i will be updating as new games release.
NOTES:
1. I will NOT be adding games to this list that had higher US pre-orders then 1st week sales in America.
2. When you see a hyper link on the worldwide numbers that means the game had a staggered launch.
3. Vgchartz pre-order numbers are not as accurate as the sales numbers so take them with a grain of salt.
4. Games that open up with worldwide sales of less then 40,000 will not be added to this list.
