I fully support miny games! A card game would be awesome. I like the idea that you need to go out and kill a bunch of things to get cards as well. Gives people a reason to travel.

I would also in Rare type monsters for this as well. So it's not only a grind thing. Could be another log you have. And it would be kind of cool if it was like a class in game. Where you would have abilities attached to your game just like crafting and gathering. But I may be dreaming too much.
