Yes, buy it. You won't be able to put the thing down either.

In terms of game recommendations:

Super Princess Peach, Castlevania: Dawn of Sorrow, Trace Memory, Electroplankton, Mario Kart, Advance Wars, Resident Evil Deadly Silence, Animal Crossing: Wild World, and New Super Mario Brothers are amazing.

And good god, what with Children of Mana, Final Fantasy III, Contact, Portrait of Ruin, and Magical Starsign on the way, I think you'd be pleased with the launch lineup by the end of the year.

I just lucked out and found a copy of Trauma Center myself today. <3
