Games for Entertaining

I don't remember the last time I played with my xbox 360. I don't have time to even bother to do any computer games except when my son begs to play the wii games then I have to set it up for him. He loves playing the Indiana Jones and Cars games in xbox, but he yells for help when he gets to the hard part. I know I have xbox live subscription, I still have unused points that I can use to buy games online, hopefully they don't expire. I heard that xbox Kinect was good. I wanted to buy it last year for Christmas but I just put it off. I thought it might just be a waste of money since we've got two game consoles already that we seldom use. But it would be fun to add to entertainment when we host parties at home. I'm sure everybody will have a blast.
