Game studio budget example

One of the members of my Game Business Channel (RU) (https://t.me/gamebizhub) asked the community: how many people I need to create a game and how to calculate how much would it cost?

PS. Do not pay attention to numbers. That is the example of calculations, not a reference for a compensation level.
