The Wii is all about fun, whether you are drunk or not (ok I'll admit it, I've never played the Wii drunk, but that's simply because I have hardly been drinking for quite a number of years now...). You had extreme reservations about the Wii, and being drunk probably simply helped you overcome/ignore these reservations and allowed you to realize it for what it really is. I think you will be able to enjoy the Wii now and have fun even when not drunk. And I think you'd be quite surprised how much fun there is in playing supposedly "casual" games you've never even considered such as Wii Sports Resort, it's mostly just a matter of letting go of your pre-conceptions.
