Galaxy 2 was bought by my gf's sister, she hated it and passed it over :)
The game is good and solid, but despite what a lot of reviews say, it could've been called Super Mario Galaxy 1.1: the engine and gfx are exactly the same, and yoshi and a couple of new power ups are not enough to make for the lost originality. New Super Mario Bros Wii is 1000000 times better.
Metroid Other M really feels like Ninja Gaiden with a laser cannon :) Which doesn't mean it's bad - but man, it's the hardest game I've played on Wii. I died like 20 times trying to kill a stupid monster. Probably the controls could be more responsive, but the worst part is the story. Don't get me wrong, I do adore some background, but in this case Samus is depicted as a very fragile woman, which is not what you'd expect from a bounty hunter. But whatever.
