We have a Wii console and we love it. We play it regularly - but not every night. Like you said, life gets too busy!
We might play the Wii 4 nights out of the 7.
I love that we play as a family.
I have a Wii also, and I absolutely love having it! I don't play it every night-- maybe every Saturday, and sometimes during the week. There isn't much consistency during the week due to time constraints.
