L.A. Noire on Xbox 360 filled six discs at one stage in development, according to Team Bondi's Brendan McNamara via OXM.
It took "miraculous compression" to fit the well-padded detective sim onto three discs, McNamara revealed. "We've always been called stupidly ambitious," he reflected. "Along with Rockstar we make very big games."
"It took a lot of effort to get down to three discs - I think we were on four or five or six at one point - and to get it onto one Blu-ray [for the PS3 version]. We're pretty pleased that we got it down to that in the end.
"It's the biggest map that we've done and that Rockstar have done, so there's a lot of detail in there, and also a lot of actor's performances - 21 hours worth," he went on.
L.A. Noire draws on unprecedented levels of motion capture data, as players read the faces of suspects and witnesses for signs of dissembling. In his review, CVG's Tom Pakinkis describes the process as "mesmerising".
