Why do you say 'Not that they are required'?
I've been looking at this game. I see it's been tagged as language dependant 0 AND language dependant 1. But, with the amount of text that looks like is on the cards, it seems like there would be a lot of down time trying to figure out what each card is used for. Or is the text mainly flavor and does it have mostly symbols on the cards to denote actions?
It is actually very easy to remember the cards just from the pictures and icons on them. We had no trouble remembering them after a few turns.
