It would be great to have the payoff time in the build order.
For instance, the next thing I should buy is Kitten managers, but as it is pretty expensive, I got a Time to buy 39days.
But maybe, the prism that comes right after it has a payoff time shorter (in my case, 9.896 quint price / 3.378 trillion CPS is roughly 34 days).
So It is pretty obvious I should buy that prism right now, since at the time I buy kitten managers, I will already have paid off and generated some more income.
Can you do anything about it ?
