Greene said the idea was to give players the feeling of starting with nothing, then finding ways to survive and eventually win. "For a title that we’ll be publishing across the globe, it made perfect sense to partner with the creator who has a proven track record of making gameplay that fans love," said Chang Han Kim, production director at Bluehole, in a statement in 2016 when the game was revealed. Last summer, Bluehole announced the game, adding Greene would relocate to South Korea to serve as creative director. That led to Greene - who went by the online moniker PlayerUnknown - connecting with South Korean game publisher Bluehole Studio, expressing interest in creating a similar "last person standing" experience.

The mods were inspired by the 2000 movie Battle Royale, a Japanese film where a group of students must fight in a Hunger Games-style competition. In the case of Greene, he created popular mods called Battle Royale for the tactical military game Arma 3 and multiplayer shooter H1Z1.

With many PC games, users use a mod to customize a game's look, rules or style to essentially create their own "game within a game." The idea behind PUBG started with a PC game modification (called a "mod" for short). "I’m the luckiest man in gaming," Greene said in an interview with USA TODAY. This week, having thrived on PC, PUBG will enjoy a new wave of players by making its debut on Microsoft's Xbox One. Instead, a combination of viral buzz through streaming services like Twitch and a novel spin on the shooter genre propelled PUBG (pronounced "pub-gee") to popularity on par with Call of Duty, with massive production and advertising budgets. PlayerUnknown's Battlegrounds is a title few non-video game diehards have ever heard of. That's partly because Greene and game developer Bluehole Studio have not marketed the game. Now he's the mind behind 2017's most popular video game. Nearly three years ago, Brendan Greene was living on welfare in his home country of Ireland.
