In a foreshadowing of the new Sim City game, this was a much anticipated release. And my recollection is that it was broken from day 1.
I made the mistake of buying it early. Boy did it crash! Just used to fall over with no warning meaning regular saves were a must. Also had a problem with some of the bigger buildings never appearing. My recollection is also that although I that I had decent new hardware the game wasn't exactly quick.
IIRC it also lacked subways which wasn't the end of the world but annoying.
I understand it was patched in the end but by then I had grown bored of it. It all rather pales into insignificance against the current games problems anyway.
