Path of Exile players love betrayal very much, it can be said that betrayal has become an iconic expansion of ARPG games. In a recent press conference, Chris Wilson stated that betrayal was the most successful expansion of Path of Exile, which has 200,000 players. Not even mainland players. Undeniably, this is indeed a very successful expansion.
“We’ve seen consistent growth up to the POE Currency three.Zero mega expansions [the Fall of Oriath, with the Harbinger Challenge League] , and since then, we’ve seen higher user numbers in both the three.30 [incursion] and also 3.50 expansions [Betrayal] , the one from December,” said Wilson. “We’re more than happy with Path of Exile’s growth over the years, especially now that it’s a game that’s been move into some form for 6 or seven years.”

Devling into the numbers
The boost in players comes of after Grinding Gear saw a dip with Delve, the challenge league that sent players into an infinite dungeon set in a very mine. This started back with the Incursion content update.
“During 3.30, we saw amount quite of players leaving as they played. During that league, people left at a faster rate than normal. We've many theories as why this might be. One amongst the theories is that there have been other games for people to play.”
Betrayal proved to be successful with the POE Items players, leading to the most effective concurrent numbers Grinding Gear has ever seen (the studio accustomed give out registered players numbers, but it’s since moved to concurrents because it looks like it’s a more robust measure of how engaged they are).
Despite this, players are still returning to version 3.50, which is very happy. When players have time to play the game, they do so. If conditions permit, the number of people will decrease when they occupy their time. But once things are done, the number will increase again.
