Nintendo's Reggie Fils-Aime has admitted that the firm does not enjoy developing mature games.

In an interview with MTV, the executive claimed that the studio could produce titles like BioShock for the Wii, but prefers to stick to family friendly fare.

"Nintendo don't create that type of content. We're not experts at it. Our developers don't particularly enjoy making that content," he said.

"They probably could make stellar content, if they chose to. We choose to do something else. So it really is up to the third party developer to create that great content and bring it to life on the platform."

Fils-Aime went on to express his disappointment at the low sales figures for mature titles such as GTA: Chinatown Wars on the DS and The Conduit on the Wii.
