Sim City DS review at 1-up.

"SimCity DS lives up to the title. Amazingly, it brings almost every classic element of SimCity action to Nintendo's handheld largely intact. Raising a bustling metropolis from barren fields involves the familiar basics of laying out the roadways, zoning the land for development, providing city services, and then cranking up the speed so time whizzes by and you can see the results of your engineering experiment. And, like its big brothers on PC, it also effectively spins the real-world clock as hours pass unnoticed while you attempt to divine the perfected feng shui of urban planning."
