The overlap in intended audience between Empire and The Hunger Games Adventures is probably vanishingly small. Both are found on Facebook but, in tone and in content, aim themselves completely different ways. It seems unlikely that very many players would approach both for long enough to realize that the two are, in every way that counts, the same game.
The former is a semi-autobiographical game following the life story of Jay-Z, from poor kid in the projects to successful rapper to wealthy mogul with a wide array of profitable investments. The latter is a book and movie tie-in, bringing a dystopic future out from the pages of YA literature and out onto the screen. One is about creating an empire; the other is about tearing one down. And yet, despite their stated differences, the two play out in extraordinarily similar ways.
