That wasnt a slump, that was an investment.
That was the money they spent on raising production costs exponentially higer than a normal gen switch, while keeping game prices much lower than they should have been for the cost it took to make the games, a tactic known as predatory pricing designed to run competition out of business, so you can scoop up their market share, while simultaneously making entry barriers too high for new competitors to enter the scene and topple you with a new exciting game concept that hadnt been done before.
as they are spending way more than they are charging their profitability goes down.
As their competition starts to go out of business, and they gain their marketshare, it starts going back up.
At that point they can start finding ways to price supra competitively, or overcharge their market. In this case they are overcharging for the worthless shit that comes in a lootbox that cost basically nothing for them to put out.
The down and then up seen in that graph is a textbook predatory pricing campaign.
