Logarithm notation is actually kind of the best option.
For those who don't know
+ 0 = x1
+ 0.1 ~ x1.25
+ 0.2 ~ x1.5625
+ 0.3 ~ x2
+ 0.4 ~ x2.5
+ 0.5 ~ x3.125
+ 0.7 ~ x5
+ 0.8 ~ x6.25
+ 0.9 ~ x7.8125
+ 1 = x10
(made knowing that 0.301 ~ 2x)
for something like 2.9 you find the 2 multiplier value, which is just 1 with 2 zeroes (100) and you multiply that by the .9 multiplier (100 x 7.8125 = 781.25)
The way to find the best estate is by doing this equation
Size ex: 10x10 would be 10*10.
size*accesibility
which ever gives the highest number is best.
i have a suggestion you should add multiple reactors and each one has its own money because i make videos about this game and i want to have a youtube reactor and a personal reactor
Thanks!
