I'm not really great at city sims but I enjoy this one due to more simplistic yet immersive environment. It's really cool being able to zoom down to street level and watch your people go about their lives. It also runs pretty well on low end hardware. I have it on my netbook which is no powerhouse (Asus EeePC 900 - 900mHz Celeron, 1 gig of RAM and Intel integrated graphics) and it runs decently enough to be enjoyable.
