As far as I'm aware, I'm all wired up, and the water is pumping freely throughout my city.
Grrr.
Yes, Theme Park and Hospital were marvellous. Used to like making my Rollercoaster go extremely fast so people fell of and vomitted.
Build 6x6 blocks of residential/industrial/commercial areas - whatever it says people want on the little meter on the left. Surround them with roads. People won't move in if a block designated for one of these things is more than 3 squares a way from a road.
Swamp the areas with power cables (not completely) connected to your power station and you're away.
Then worry about a few water pumps and pipe them up.
Stick in the occasional Bus Depot, School, College, Park, Hospital, Prison, Police Station, etc.
