As I've said a couple of times now, I'm in the process of developing a Fantasy Boardgame which will contain basically everything (minis, tokens, cards, and dice)
I thought though, when you consider the amount of games that use cards with subtexts along side the actual statistics/abilities of the cards, most of the subtexts are generally just flavorful quotes. I haven't ever personally played a game with cards that have game history scrawled on them.
And then I thought to Dark Souls: Most ALL of the important historical information is attached to the items. Call it a rip off, but I think it would be clever to do the same with Card items and spells and treasures and such.
Thoughts?
