Here is my opinion! I live in the states so idk if that matters but anyway I play kinect sports is easy to find people to play with and I would say the best games are as follows:
EA sports active if you want a work out game
If you have children
Game party in motion
Sonic Racing (I found that fun personally)
Games you may want to avoid or maybe rent first
Fighters Uncaged has been poorly rated
hope that helps! if you have any other questions you might wanna ask just send me a message to my xbox account I have owned a kinect since day one, write for a gaming website, and do a lot of research weekly!
