"Should the cards be embossed?"

I can't say. What is important is that they be authentic. Don't hide behind fancy embossing and gilded flourishes if they aren't you.

First -- what kind of paper? Utilitarian card stock from staples? Low environmental impact bamboo weave? Flat or glossy?

Then ink color, font style and size, etc...

What about a photo?

There is a lot to consider, but when it is finished, it should feel like it screams the inner Wii to you.
