Most important to start with a solid foundation when building a game on new hardware.
FIFA 13 will not feature popular game mode, Ultimate Team, producer Matt Prior has told NintendoWorldReport.
Although the mode has become a staple of the current-gen FIFA games, building a game on new hardware means getting the foundations sorted is most important.
"With new hardware, one of the challenges is - unlike PS3 and 360, where you've got a game, it's finished, it's done, and you build on top of it next year - we don't have a game," explained Prior. "So we have to build that foundation, and just like building anything, you need a solid foundation that's stable on which to build."
"We have to take a point in time when [the game's] stable and then bring it over and then all the work we're building on top of it, so in terms of where this is at, it's not [FIFA] 12, 'cause there's a lot of enhancements from 12, it's not 13 - it's kind of somewhere in between at a core level."
Sadly, one element which had to be cut is Ultimate Team.
"We wanted to make sure we got the most popular feature in [versions for] 360 and PS3. Either online or offline, the most popular feature in it is an online mode called Online Seasons, so that's in the Wii U [version]. Some of the more advanced [modes] that took many years to kind of come onto 360 and PS3, things like Ultimate Team, they aren't on it at launch, but the biggest one in terms of popularity is."
FIFA 13 will be released September 28 on current consoles and later this year for Wii U.
