"It's certainly a big relief that the company is profitable and that we don't need to worry about whether the game will be successful or not any more," Wilson said.
The 31-year-old explains that gaming has been in his blood from a young age.
"I grew up playing games on my Commodore Amiga computer and dreamed of becoming a game developer when I grew up.
"This led to me studying computer science at university," Wilson said. "The feeling of having people play a game that you created is really fulfilling and addictive.
"Each review and discussion thread online is great motivation to keep working as hard as we can."
At the start of the year, the company had 22 team members. That number has now swelled to about 55 to handle Path of Exile's popularity. And next year is shaping to be just as busy.
Wilson is planning to push the game to even more countries.
At the moment Path of Exile is available only in Western markets.
"There are many more large territories (such as Taiwan) that have shown great interest in Path of Exile but can't currently play easily because we don't have local servers in their area or a version of the game available in their language."
