Obviously it would be updated and built on from its FM2023 version, with a couple dozen square miles of surrounding area/roads and extra stunt jumps and other assorted Horizon features. For me, it'd be a fun addition, especially if they bring back all the point-to-point variants in both directions, and they could add those drift attack features and new touge races, too. It's still a huge shame that it arrived in FM2023 just in time for the game to become completely irrelevant. But the way the online fanbase is going, how many people would pitch an absolute fit for having to pay for "recycled" content, no matter how fun it would be in FM6?
