inFAMOUS: Second Son just surpassed Titanfall (Xbox One) in Amazon's March Bestseller List
I think this is pretty interesting considering the difference in marketing budgets between the two games and the fact that PS4 and Xbox One are pretty close in sales in the US. inFAMOUS: Second Son is turning out to be a bigger seller than anyone expected.
Still, it's pretty much a given that Titanfall (Xbox One) still outsold inFAMOUS: Second Son thanks to the bundles that basically gave Titanfall for free and in some places was even discounted by $50. That brings the question as to why didn't Sony bundled inFAMOUS in the US just like they did in Europe, specially with the PS4 still selling so much, that would have boosted the sales of the game significantly.
