Do most gaming companies give out bonuses when a specific game does well and does everyone receive it? Do certain companies/groups not receive any bonuses?
Yes, but there is a caste system. The closer to the actual development of the game you are the higher on the ladder you are.
Spot on, the game studio that generate the most revenue gets the most bonus.
You are much more likely to get laid off than get a bonus.
From the news I’ve been reading they typically lay folks off after a game is released :( regardless if it does good or not.
