Episode 3: What 3-bonus combos to prefer on Biomes of AmericasIf you possess a certain level of skill, you comprehend that cities and crude oil bonuses on Biomes are superior to other bonus types because they give you more income per territory. If asked openly, most players I know answer correctly that these are the best. However, when asked what bonus type of 3-bonuses (bonuses that give 3 income when completed) is the best, most players choose the wrong answer and pick accordingly.
Consider the following scenario: Everything else being same, you can choose between Northern Amazon as a first turn bonus (a rainforest, let‘s say the picks are Manaus and Paramaribo) and Northern Great Plains as a first turn bonus (a farmland, the picks being Edmonton and Montana). Both bonuses consist of 4 territories and give 3 income when completed. Now you have to decide which combo to prioritze / pick first.
Most players prefer the farmland because it doesn‘t give negative income. They don‘t realize that the negative income you have after picks (turn 0) almost never matters because you are excessively unlikely to have any income that turn anyways. They are also scared of having negative income later if they fail to defend their bonus, which makes even less sense (read on to learn why).
Now let‘s do the math: Imagine you picked the farmland in the example above and your opponent picked the rainforest. You both took 3 income turn 1 without deploying, so the situation is equal. Now your opponent successfully attacks you and takes one territory from your farmland bonus. What happens to the incomes? You go down from 3 to 2, he remains at 0. In total, that‘s a -1 for you,.
Let‘s go through the alternative scenario: You make it to the opponent‘s rainforest bonus and break it, taking one territory. He goes down from 3 to 1 income, which is a loss of 2, sounds worse than your loss above. But what happens to your income? You go down from 0 to -3, which results, in total, in a -1 for – again – you, compared to you opponent. Sounds bad, doesn‘t it? He broke you and you lost income, you broke him and you lost income. Something is wrong.
Rainforests, or (if you want to apply this to other INSS templates) bonus types that give negative income for few territories, are preferable as FTBs compared to bonuses with the same efficiency (income per territory), but without the negative income feature. The reason seems straightforward, but is missed by most players: If you hold a rainforest bonus, you are more difficult to attack. The opponent basically needs to take two territories from you (in the same turn!) in order to create a positive income effect.
(Needless to say that if you take two territories rather than one from a bonus that consists of four territories, the income effect will be equal regardless of the bonus type because both players will be holding the same number of territories.)
