I bought SimCity 4. I played it for a while - built a number of cities...even had a few different girlfriends build cities, but eventually got tired of it and moved on. It was nice that they were finally incorporating neighboring cities into the patterns of the residents, but I admit that I did not realize the level of this until right before I became interested in something else. I never really took advantage of it, but that was how I would have been able to unlock the Spaceport bonus which is what I really wanted. I remember something like the need for 25,000 high tech industrial jobs to get that, and I could never get more than 20,000 even though my city tile was completely built out. Alas - if only I had had the patience to keep playing, that would have been how to do it.
SimCity 5 looks like a mess, though.
