Child of Eden I can agree with. It works well even if I still feel the lag. It's a lot of fun to play on Kinect. I prefer the PS3 version only due to stereoscopic 3D + Move (which is trippy as hell when played on a Sony HMZ-T1).
Gunstringer is pretty simplistic as well, but a fun, well produced game. Perhaps the best Kinect-only title to date.
I didn't think Kinect Sports worked all that well as they subtracted even more interaction than Wii-sports.
Dance Central is also pretty awesome.
I still feel as if all of them are very surface, though. They don't really do anything really unique with full body motion. Dance Central is kind of there, but they obscure a lot from the user. Most of the games seem to track VERY basic motions or turn your arm into a cursor. Both are neat, but I was kind of hoping we'd see a lot more. The Kinect is more than a year old and there is still very little on the horizon promising something new.
I definitely do not HATE Kinect, though. I don't really hate any game hardware, to be honest, as I tend to buy most everything. I did not buy a Kinect but I did spent a few days with it in my gaming area a month or so ago. It's definitely much better at home than in store, I can admit that much.
Try Winter Stars and the Snowboarding and Biathlon events...they are not just simplified movements.
I think once you get the hang of Table Tennis on Kinect Sports it's a really decent attempt, miles better then the dumbed down Tennis on KS2. Kinect Sports has some reasonable games and I know a lot of people who have sold their Wii's and got this instead. Yes some of it is very basic but it's still good fun too and much more energetic then Wii sports ever got in my opinion.
Your Shape is a damn decent piece of software too.
People go on about how many games does it have that are decent, it depends on the individual and what they like. The same could be said of the Wii. I think the Kinect is a decent bit of software and great family fun.
My daughter and I have great fun on Kinect Adventures, especially the rallyball and river rapids.
Kinectimals is short term fun for her and she plays it in bursts. It looks good but is a definitely a kiddy game, that even they get bored of by a certain point.
My friends and I get great enjoyment out of Kinect Sports 1 and a bit out of Kinect Sports 2, KS2 felt half finished.
Dance Central as mentioned is great, if you have rhythm - I do when pissed.
Your Shape I enjoy working out too when I can and think it has some decent workouts.
I also have Fruit Ninja which my daughter and I like playing now and then. All in all I have had over 200 hours of fun on my Kinect already easily. I like it and isn't fun what it's all about at the end of the day?
