Addicting
I used to play this alot and once you get the beat down it gets super easy.
You only need like 3 Crop fields and 4 for Cows and when the land starts to die.
Sell it and put the cows somewhere else the land becomes fertile again. And you can continually do it and if you need too use the rainforest.
I got the 2040 no problem and am still going.
