My main issue with this game is the amount of space you need to devote to utility buildings.
What world do the Maxis devs live in?
One nuclear reactor should power an entire region. Hell, one fully upgraded coal or oil plant should power a region with five cities.
Same goes with the most of the other utilities. If you force us into small tiles, then these buildings should service far more people.
I have a four reactor plant in Whitewater Valley and it's not enough to power four cities totaling about 300k in population.
200 MW from 1 reactor is also half the amount of energy produced from the smallest reactor in the USA.
