I am now the proud owner of the board games - we do a lot of gaming, so they won't be bought in vain!
The Arcanum deck is 90% Initiatory Tarot of the Golden Dawn, just cards with nudity (e.g. Lovers, Star) are replaced with cards from Ludy Lescot, as well as some random others, for example the Aces. If used as a Tarot deck, I think there is a kind of break because Ludy is in these soft dark blue hues, whereas Initiatory is quite bright and crisp. Since there are few Ludys, I don't think it really matters though.
The deck is supposed to be "family friendly" ... in my book, nudity wouldn't be much of an issue, slightly gory cards like the Queen of Swords with the traditional severed head and the bloody sword more so, but they left her untouched! Ah, the dangers of a bare butt!

ETA: The Majors have green backs, whereas the Minors have red ones - good for a boardgame, bad for readings!
