Yeah, Hey Ya is one of my son's favorites too.
I feel that for SingStar, they should have gone a different route. Karaoke is about self expression. I feel that the dance module in SS should have been for self expression instead of following a fixed pattern (for scoring or education). The SS Online videos will be a hell lot more entertaining if they allow people to dance freely.
I want to see real people dancing in SingStar, so avatar dancing is out of the question.
They only need to add a good variety of supporting dance cast to guide us. They can also do 2D image processing to blur our faces (or replace our faces with cartoons) if people are shy.
There is a black family imitating the Jacksons 5 in SingStar Online (4-5 dancing kids and 2 adult guitarist behind). I think something like that would be the right mood. They should not get carried away by technology for technology sake. Should be more like LBP than an inhibiting dancing game. ^_^
EDIT: Just want to update our experience. Amazing how it changed when my wife came back from her business trip. The game is a lot more fun when there's a woman in the house. ^_^
She cracked up when she saw the father and son dance in her living room. In the end, all 3 of us ignored the scoring and danced to our hearts' content. We followed the dance steps but improvized them. We found the "Full Video Playback" option, and made a few videos, but there's no way to send them to our friends directly from the PS3.
They should let us upload to Facebook or regular email.
We find that the easiest song to start is: "I Like to Move it". The game should be renamed to "SingStar Performance". We switched to karaoke when tired, and then back again, and also compare with other players' performances online. It's a pity those videos can only be viewed by SingStar gamers.
Yeah so, I still think they should not use the Move controller in this game. Include the dance moves but let us perform at will. Use the community to judge our performance. Use technology to hide our identity but let everyone see the live performance (Not avatar performance).
