Best answer: The DLC expansions will absolutely be worth buying, but the Ultimate Edition or Ultimate Add-Ons bundle represents better value.
Two confirmed expansion packs
Forza Horizon 4 players are being treated to fresh content on a weekly basis as the seasons change and through regular Forzathon challenges, but the expansion packs offer something much more.
The first, Fortune Island, is already available and gives players an entirely new map to play through with additional races, stories, PR stunts, and achievements to enjoy. It includes the longest Driftzone in any Forza game to date and the terrain is quite different froming t the main map.
There will also be another expansion pack for Forza Horizon 4 but as yet it remains unannounced.
Ultimate Edition represents the best overall value
The Ultimate Edition of Forza Horizon 4 is pricey, but as it also includes the DLC expansions, which means it represents the best overall value. If you’re not yet playing Forza Horizon 4, it’s the one to get.
