Had to look in my spam. But anyway. Horribly translated from german:
edit: Ok, there's a catch. At the end of the email it says that the comparisons are only made with people who also get this kind of e-mail. I would imagine that is not everybody on the PSN. I would never be in the top 1% with my lousy trophy collection. Plus, I tried to extrapolate some sales numbers out of this (I just can't help it!). If only 139 people have the Bring them All on trophy from Mega Man Legacy Collection, that would mean the game only sold about 4,000 times, because in the trophy list it says it is obtained by 3,7 % of players. I have a hard time believing it sold THAT bad.
So yeah, the whole thing is probably not worth too much, but still fun.
Yup, that seems to be the pattern.
