What should I know before buying a Wii and Xbox 360? Additional Qs inside.

As some of you already know, I have become slightly obsessed with the Wii as of late and so have decided to buy one for myself. My brother wants to buy the Xbox 360, groan which I have no interest in whatsoever, but I was wondering if we would get a better deal if we tried to buy the two together? Should I just try bugging bargaining with the folks at GameSpot?

ALSO, the Wii I currently play with is my roommate’s, and my Mii in it has racked up a lot of points and even PRO in some sports. So I wanted to know if there’s a way I could move my Mii from her Wii to my Wii using a physical card as opposed to using the Mingle feature? Yes, I do realize how ridiculous and dirty that sentence sounds. For reasons I’d rather not go into, she doesn’t want her Mingle feature enabled, plus I am pretty sure she doesn’t have internet to connect her Wii too (assuming that’s how the mingling happens?).

Bonus – I know that I want Mario Kart and Wii Fit for sure. But if you have any other games to recommend, go for it! I am 20 years old, and prefer games that involve actual physical activity as opposed to sitting down and using the Wii remotes as a controller. But I am still open to all suggestions. Don’t focus too much on the bonus though, because I already read the amazing answers posted on this question by bythebay and this one by dandydear about it.

Lastly, and this is really rhetorical, but WHY IN THE WORLD is this thing and its games so darn expensive???? I haven’t bought a console in too long, but the amount of profit they must be making on these systems is kind of sickening. Ok, end rant.
