I feel if you go towards the 7 deadly sins you will lose a lot of your potential christian market. keep it more cheery and you have families who would buy a deck to support you. 7 deadly would not get you that. Would you want your child playing with a deck that talks about the 7 deadly sins?
Why not? It's in the Bible, isn't it? How can you avoid the 7 deadly sins if you don't even know what they are?
I don't know that I want my child playing with an angels and demons deck. But to Don's point, it would be easier to separate out the good and bad forces (duality). it just seems that this deck concept started as a 'Heroes of the Bible' and has now gone to 'Angels and Demons'. If your target is a Christian market, would a deck about battling mythical creatures (and yes I said it) be more popular than fundamental biblical characters? I think if I show up to sunday school with an Angels and Demons deck I might get the boot. (FYI - I believe in Angels and Demons, just without the wings and so literally battling for the human race).
But as we haven't seen anything of this deck otherwise, all i can go on is the card back which I do like. I think it's very artistic and appealing. IMO.
If you showed up to Sunday School with an Angels and Demons deck - and the Angels were WINNING - that might be a different story...
As was pointed out, he's planning a series of decks and talking about them pretty much all at once, so I can understand if it seems a little confusing as he shifts from one deck idea to the next. My advice, xx789m, would be to stick for now to a SINGLE IDEA and see that to fruition before chasing down all the other ideas, because a) we have yet to see you deliver anything, and b) it makes you sound like a jack-of-all-trades, master-of-none, when you should simply sound like a master. Stop talking the talk and start walking the walk. (And choose a board name that sounds more like a person and less like a pornographic droid...)
