I love them. I used to play SimCity2000 on SNES all the time, it was crap, but it was awesome. Last year I wasted a few months playing Sim City on my PC. I like being clever enough to make a successful city, and then be greedy enough to ruin it all by aiming too high
i love simcity as well, i'm just addicted to games with numbers, as in the money you make, the population etc....
