SMG2 should be as much as any sequel has been this gen: a 1-2 week HW spike then a return to the pre-release baseline.

I have no clue about Metroid. How popular is the franchise? Is there something particularly special about Other M that the other Wii Metroids don't have?

Highly accessible 2-D gameplay requiring nothing but the nunchuck.

I thought you only played it wth only the wii-mote horizontal, and if you wanted a 3-d view you used the ir pointer....
