Researches

Scientists
Balancing your scientists is an essential game component and should never be overlooked. Scientists unlock and maintain critical bonuses for a competitive Kingdom, and are built into the game to balance against exponential growth once a certain KD gains a considerable advantage. There are dynamic bonuses which must be maintained based on your total land, and static researches which unlock additional technology to considerably empower your kingdom.

It's difficult to design a general catch-all formula for sci count, but if you're totally new to scientists - keeping 2-4x your land in scientists as a rule of thumb will typically let you maintain most of your researches until you have a better understanding of them. Researches progressively increase in difficulty to maintain as your kingdom, so the later the game has progressed (and in theory as your KD grows), it will require a higher "ratio" of scientists to maintain.

Land Based Researches
Land based Researches improve the efficiency of your kingdom.

The points needed to maximize these researches increase based on your land.

In game you can see how many points are required in order maximize these researches.

The formula to calculate the amount of points needed to maximize a land based research is the following:

Research Points Needed = land x land x factor
