Aug 3 (Reuters) - Video game developer Atari reported annual revenue of €56 million ($65 million) on Monday, its ‌highest in more than a decade, as a ‌strategy built on reviving old franchises and buying up studios pulled ​the Paris-based company back into profit. Atari, the arcade and console pioneer that filed for bankruptcy protection just over a decade ago, is riding a broader industry shift toward ‌mining back catalogues ⁠and nostalgia-driven franchises instead of costly new blockbusters, a trend it has embraced through ⁠a wave of studio and IP acquisitions over the past year. Over the past year, Atari raised its stake in ​Swedish video ​game publisher Thunderful to ​97%, bought Crossy Road-maker ‌Hipster Whale for $29.3 million and the IP rights to five Ubisoft titles, including Child of Eden and Grow Home. • CEO Wade Rosen said Atari was "reaching operational profitability for the first time in several years" and that he ‌was confident it would continue ​to generate sustainable growth• Atari's Games ​revenue rose 67.7% ​to €46.1 million, while Hardware revenue jumped 83% ‌to €7.3 million• Current operating income ​turned positive ​at €0.9 million, versus a €0.8 million loss a year ago, excluding Thunderful• Net income excluding Thunderful was €0.1 million, compared ​with a €12.6 million ‌loss last year; cash flow from operations was €11.0 ​million($1 = 0.8674 euros)(Reporting by Leo Marchandon in ​Gdansk, editing by Milla Nissi-Prussak)
