As MediaPost reports, the Nintendo Wii has been recently hovering in the top spots of Amazon's wedding gift registry. Their observation that "Nintendo is no longer seen as an obstacle to a healthy marriage, but as a contributing factor," is very consistent with happenings in my own relationship.
My wife and I find that by participating in Nintendo Wii 2-player bowling or tennis, it brings us closer the way actual sports and activities tend to do. There's usually a hand-slapping "good job" to commend a nicely bowled strike. Or, a thorough taunting when my tennis serve is an ace (well, in all honesty, the taunting isn't always welcome).
