It’s been a long, long time since I last played SimCity, so I don’t really remember what I’d done back then.
Apparently I, the mayor, had almost bankrupted the city two or three decades ago, and am about to repeat that it seems. I also seem to have unleashed some sort of epidemic or healthcare crisis four years ago, which killed everyone above the age of five. So I guess I now have a population of 533,701 pre‑teens.
(Edit: Just checked. Half a century ago, I decided to mow down a large part of the city. I guess it killed a lot of tax revenues and took a while to regenerate, which is how I almost bankrupted it.)
