Loving the Wii

So we finally got a Wii! About time right. Everyone else and their brother has one. Now I need to figure out which fitness game I want for it. There is Wii Fit, EA Sports Active, My Fitness Coach, Jillian Michael's Fitness Ultimatum... I am sure there are even more out there that I haven't stumbled across. So help me choose. What do you have and what do love/hate about it? Is there any separate equipment? What will help me lose weight and get fit the quickest? What can I do without accidentally hitting, kicking or falling on a kid (since one is always under my feet!)?
