“To become the most successful launch in Korea for over three years is an incredible achievement,” said Bill Roper, CEO of Flagship Studios. “This milestone wouldn’t have been possible for us to achieve without the incredible support of our publishing partner, Hanbitsoft, and our dedicated community in Korea. We look forward to expanding the Hellgate universe and building upon this success in the future.”
“Flagship Studios are well aware of how the Asian market operates very differently to the Western territories” said Alex Kim, CEO of HanbitSoft, “By listening to players’ feedback and through constant updates to the game, Hellgate: London will continue to be an incredible success throughout Asia.”
Hellgate: London was released commercially on February 22nd, and achieved record sales in its first week of presales.
I'm pretty sure you have to actually sell copies and be out of beta to have a "successful launch".
