better on kinect? bold claim and I highly doubt it, at least when compared to keyboard/mouse.

Though I can definitely see it being better than the 360 control pad. 

they aleady got to the modern age or near enough, they cant go to advanced. I want them to HD-erise age 1 though

That would be awesome, although Age Online is set in that time period.

Because of the name I doubt it is single player unfortunately. I hope so. 

It does actually have a significant single player component. You use the home city to access single player "quests", which essentially equate to the campaign and scenario mode of previous games. They then give you items and XP which allow you to unlock tech and units at your home city (a bit like AOE3 but with more customisation).

There are a few quests that you have to do co-op and you can also access PVP matches from your home city too.
