Titanfall release date: mar 11 (5 days in first week)
Second Son release date: Mar 21 (2 days in first week)
So the Sony exclusive sold more per day even including the staggered international release.

Also, vgchartz tends to be way wrong.

Yes, let's trust the site that looks like it was made during an beginners' HTML course, has pink buttons and cites no sources over the actual widely-trusted sales analytics website.
