Recently picked up the new Nintendo DS with a copy of Super Mario 64 DS. I really couldn't afford it both money and timewise, but it is really great. Super Mario 64 is awesome although frustrating at times. I work on a computer typing and manipulating a mouse all day long no problems, but using those little buttons and trying to get those freaking characters across narrow bridges and to jump at the right time and I think I am giving myself carpel tunnel!
I just rented Urbz and Spiderman 2 for the DS from Blockbuster. Spiderman 2 has great graphics, but the levels are hard and the controls are hard to get used to. I would not have bought it, but for $6 to rent it for a week is about right. Now, Urbz is a great game, my daughter absolutely loves it and we might have to trade in some of her old GameCube games in to get buy it.
Can't wait until Wario Ware and Advance Wars is released for the DS. My daughter is looking forward to Animal Crossing and Harvest Moon. Better start saving now.
