If you notice CE is just like gasoline we have to pay for it to run it (except theres no mist gasoline cause we are all going to die breathing it)
gasoline price has raised pretty high
CE has SKYROCKETED
if you goto a another city it'll probably cost 20-45$!
if you want to 7500CE its about 20 and it goes out fast depending on how you use it.
they are pretty much the same...

Gasoline is not a good analogy for CE, since there are alternative energy sources such as diesel (bio or otherwise), ethanlol, electric, and hydrogen fuel cells (essentially fancy electric). There is only one choice for us, CE.
CE also only changes its crown price, its actual purchase value with real money never changes. So it's like paying for gas with BitCoins, only you can't right now.
