There is a vocal minority who want to turn FH into “Underground 2023” because of their deep, nostalgic love for The Need For Speed Underground games that took place in big urban cities. Some are Midnight Club, fans as well.
I state this not to be antagonistic, but give some insight on why this vocal minority will never be happy with any expansion that doesn’t live up to their projected expectations:
Many want an urban racing game with Horizon’s budget and feel, or more specifically, wanted an urban expansion in FH, so they can relive the fun they had as a young child when NFS Underground 1 & 2, released. Many have stated, it was these games that introduced them to car culture and JDM culture in particular.
They’re wanting to relive that sense of awe and wonder, but no other (big) racing franchises has been able to provide that for them. So, they always hope PGG will “listen to the majority” (that’s a minority) and just make “Forza Horizon: Underground 202X”, so they can relive those childhood memories and get their hit of nostalgic dopamine.
There is nothing wrong with this, but Forza Horizon is meant to be a game that celebrates general car culture from around the world, and it doesn’t focus on one specific type of racing.
Fans can debate whether or not the series is doing this well or not on their own, but the underlying point is Forza Horizon is never going to be the big budget, urban racer a lot of fans are hoping for. This hope stems from childhood nostalgia, and no racing game is ever going to live up to.
Underground, and the Midnight Club series hit at just the right time when the pop-culture zeitgeist couldn’t get enough of automotive culture thanks to “Fast & Furious”. This era also marked the same time many of these vocal fans were very young and experiencing both video games and car culture for the very first time. Hence, they want to relive those more simple and happier times now that they’re adults and get subconsciously upset when no game allows them to do that.
