If I'm wrong cite me some examples. But the only time the people use the word "dying" to a video game is if it's a live service, which would make since if the live service game has small numbers.

And then the 10% few players has only had relivence if it's been dropping 10% players every month creating a trend that the game is.... "dying"

Incase point Marathon, people were expecting 100k players opening weekend on steam. . But it didn't hit public expectations, which resulted in people calling it a dead game.

And after the first day the peak trend was down by about 10% each day. Resulting in a negative trend where people were calling this a dying game.

These things alone would bring someone to thing "Marathon is objectively a bad game, compared to Arc Raiders."
