So why is it represented as 99.999… Instead of just 100? It’s because you’re forgetting the fact that fractions and decimals are infinite depending on the magnification. 99.9999… literally goes on forever. That means that no matter how close it gets to 100, it will never be equivalent to 100.
It’s like how you can know infinitely nothing and still think you know everything. 👀🫠
Even if it’s not an MMO, player count can be a very strong indicator of enjoyment/income at a given time. Even if it’s a single player game, player count can show how popular a game is on whole. If a 5yo game still has engagement numbers above newly released games, it’s strongly correlated with studio income/gamer trends.
They can base future decisions on what they did correctly/incorrectly, and develop their next game/dlc/etc with those lessons learned.
Release a game that has nobody playing after a month? Crapbasket. Release a game that has well into a million players despite the age? Fucking masterpiece.
