Nintendo games are barely educational. I can't think of anything anyone could learn from Brain age for instance. It does indeed use thought, but it doesn't teach any skills/knowledge. There is a difference between trying to pop balloons in numerological order quickly and learning about the History of Germany from Carmen San Diego.
If just basic mini games are enough there is Hot Brain on the PSP and others for PS systems as well. I'm not saying those games are useless, just that they aren't quite educational.
I can't think offhand of any MS games that are even remotely educational in nature however, though I do know several for both Nintendo and Sony. Maybe you could say that practicing marksmanship vs aliens counts?
