Cheers Don. Yes it's certainly an alternative take in many regards.
One point is that that Tarot de Marseille style decks were used for gaming in France until relatively recently, even after the introduction of the French suited Tarot Nouveau. And this type of traditional imagery is still found on standard Italian tarocchi decks used for gameplay. So I don't think there's anything /that/ unusual about using a traditional(ish) design for gameplay.
I think the gaming tarot market is a tiny fraction of the whole, though. Probably most people in English speaking countries don't think of tarot as a game at all. I am not sure I had come across it before I lived in France. Nevertheless, I think playability is an important design consideration, for these as much as any of my other far-out decks.
So yes, then it comes down to the trump sequence and the significance of the illustrations on each of the cards. And you are right, they are not the same as the typical Marseille illustrations. But to get there I studied a lot of historical decks, each with its own take on the indvidual illustrations/ideas and on the sequence as a whole, and this is what I came up with. I guess it's my take and some people will like it and others won't.
The court cards are the same though between divination and gaming decks. They all have king, queen (or dame in French = lady), knight (on horseback, chevalier in French), and page or jack (both called valet in French). I don't know why in the Rider-Waite deck they decided to call the jacks pages, but they did, and it has stuck in such English language divination decks.
Hopefully enough people will like it. We shall see.
I can certainly sympathise with the can't buy em all sentiment!
