Why would it take more than 2 and a half years to make a remake of VII?
They've got an engine. [FFXIII]
They've got the locations.
They've got the script.
They've got the character models [Crisis Core/Advent Children].
They've got the voice actors. [Crisis Core/Advent Children]
GT5 was built from scratch, took 5 years with 110 employees, has new licenses from around 2 or 3 new car companies the past games didn't have, a number of new licenses for events and tracks, a heavy online component that an FF doesn't need and has visuals a FFVII remake wouldn't need too match. Yet it's at a 60M budget. How expensive and time consuming could an FFVII remake on PS3 be?
