The work is worth it, in my opinion. But the sales page, etc. can be pretty damn confusing, with specials, overlaps, etc.
For example, "Nefertiti" at first just seems to be his "Cleo" package but with a white woman and family (not at all accurate) in place of the far more accurate Egyptian woman and family. But there also seems to be icon differences as well. AND "special editions" for everything.
So between "Pharaoh" (4 editions!), "Nefertiti" (2 editions), and "Cleo" (2 editions), I have no idea what package I want to buy to get a full Egyptian-themed set.
And no, I won't be paying $50 for icons just because his website is confusing and doesn't enable me to compare the sets.
