Eurogamer has posted a fascinating interview with Tomb Raider's executive producer Scot Amos, discussing the game's long-awaited ascent to profitability. Despite developer Crystal Dynamic's critically acclaimed reboot of the Tomb Raider franchise, the game's release did not achieve the meteoric sales figures (3.5 million in month against expectations of 5 million) that Square Enix hoped would propel the franchise, and the publisher itself, back into the black.

"By the end of last year - Tomb Raider is in the black," Amos revealed. "We've crossed the line of profitability for the last-gen and PC versions."

2013 was a roller coaster year for Square Enix. After a management shakeup designed to counter growing financial problems facing the company, Square Enix apparently returned to form with the reveal of Final Fantasy XV and Kingdom Hearts III at E3 in addition the release of Final Fantasy XIV: A Realm Reborn. Later this month Crystal Dynamics and Square Enix will publish Tomb Raider: Definitive Edition for PS4 and Xbox One, featuring new physics, character models, and improved environment effects.

"This was in the bag and on the way even before anything happened with sales expectations or where things were at. We were having this conversation at the end of 2012 when we first heard details and rumours of next-gen consoles."

Both companies have confirmed that a sequel to Tomb Raider is in the works, although relatively little else has been revealed. Tomb Raider: Definitive Edition will launch worldwide in the last week of January.
