We love board games. My kids are older so we go for more sophisticated games like Settlers of Catan these days, but we have collected quite a few. I know what you mean about kids being good at memory games! Our kids have always creamed us at those too.
I can't wait till we hit the more interesting games! I hope that they still will be interested in those! Memory... kids, they are freakishly good at it.... sometimes, I don't even get a single pair!
