I`m afraid that`s either a very naive comment Cynthelion, or an exceeeeeedingly great understatement... let`s take a look:
Research lvl:
Commerical - 0
Agriculture - 0
Base income:
Commercial - 5
Agriculutre - (food at 13) X 1.2 Terran Ag bonus = 15.6
There is just no comparison to be made here at all. This calculation does`nt even factor in the bonuses that come in if you have clusters, or forest planets, or U. fertiles.
