I'm not sure how things are recently, but it has been/was a common thing for companies to try to get you to do this. For example one of Japan's biggest pop idol groups (AKB48) would host voting contests where they would release a music album, but that same album would have several reprints, each one featuring a different girl on the cover. 1 copy of an album with her on it = 1 vote for that girl. And it was absolutely encouraged to buy multiples of the same CD to cast votes for your favorite girl.
This sort of practice stemmed from targeting dedicated fans in niche markets for as much money as possible after Japan's last big economic bubble popped and general consumerism declined, except in niche fields like certain entertainment subcultures (like anime and video games). The short of it is companies learned that hardcore fans are willing to spend huge amounts of cash to support their hobbies, and they capitalized on it.
This article series puts it way better than I could:

This is the specific part of that series that mentions the CD phenomenon with AKB48:

So long post short: absolutely I wouldn't be surprised if that was Square Enix's end goal.
EDIT: for those that don't want to read the whole thing, I'll post the AKB48 bit
