By the end of the publisher's financial year on March 31, 2013, the games moved 3.4 million, 3.6 million and 1.75 million units respectively outside of Japan and excluding digital sales, results previously described by outgoing company president Yoichi Wada as "weak".
And this week he said: "Financial year 2013 was our first big attempt to release hallmark western titles, such as Hitman and Tomb Raider, without releasing a blockbuster title in Japan.
"We put considerable amount of effort in polishing and perfecting the game content for these titles, receiving extremely high Metacritic scores. However, we were very disappointed to see that the high scores did not translate to actual sales performance.
"We do not disclose the number of sales units anticipated in our forecast, and although I cannot mention exact unit numbers, I would like to touch on how we approach these sales figures.
"Let's talk about Sleeping Dogs: we were looking at selling roughly 2-2.25 million units in the European/North American market based on game content, genre and Metacritic scores.
"In the same way, game quality and Metacritic scores led us to believe that Hitman had the potential to sell 4.5-5 million units, and 5-6 million units for Tomb Raider in European/North American and Japanese markets combined.
"Of course, we want to hedge risk in budgeting these directly into the forecast, therefore we base the forecast on 80-90% of the total sales potential of each title. However, it is disappointing that our results fell below these marks."
