Why don't certain Ps3 games (Infamous series) sell good?

First off, I don't think 1.28M retail is a bad number for an exclusive. It's not fantastic or anywhere near the upper echelon, but it's not bad.

Second, it's going to get harder and harder to compare sales of newer games to those of older games. InFamous 2 was released as a day one digital title, if I'm not mistaken, and was also used to leverage PS+ as a free game. Now it's in a collected release format. What if none of those things had happened and it was simply sold in the standard format like the old days? I think the actual retail sales number would be quite a bit higher.

With the rise of digital distribution, only the publisher can really say how successful a game is in relation to older entries in the series.
