Where do I even begin… The whole Upgrade & Tuning System needs to be replaced with a new one, but really the thing that bothers me the most is the amount of Upgrade Tiers we still have. Let’s be honest, 3 isn’t enough. It was just right on the Xbox 360, felt okay on the Xbox One, but since FM is supposed to be Built From The Ground Up I was really hoping that it’d finally ditch the Upgrade System that’s functionally identical to the one in the first Forza Motorsport on the original Xbox.
Many engines in real life can produce amounts of power which Forza can’t even calculate, mostly thanks to the in-depth modifications that can be done in real life. While I do realize that bespoke parts would be too much, we need at least 2 more tiers of parts. The difference between the current “Street”, “Sport” and “Race” should either be smaller, or bigger but with intermediate parts in between them. And they should change the names too, but that’s besides the point. Currently, maxing out a 2JZGTE in FM aside from Turbocharger upgrades will put it at around 840hp, and when you apply a Sport Twin Turbo it suddenly jumps up to 1050hp. A Race Twin Turbo will give it another 140hp. I’ve just checked and the numbers barely differ between TT and a Single Turbo. Either way, as far as I know these engines tend to withstand even more power, even though it’s kind of unnecessary, so tiers both lower and higher than the currently available ones would allow for a lot more room for upgrading cars, and that’s just engine upgrades! Imagine Tiers of suspension with different adjustability levels, because you don’t always need the entire slider. Similarly with Gearboxes, or Differentials, or even Stabilizers sometimes, and Aero too!
The current 3 Tier system is basically “Nothing, nothing, almost nothing, everything”, which most of the time makes Street and Sport upgrades legitimately useless. I know it does leave me wondering why they’re even there in the first place when I don’t know what’s the exact performance difference between them without driving the car and paying really close attention. Unless I don’t know about something and there’s some kind of system that makes them exactly just enough so that I don’t need to spend extra credits on adjustability, but also exactly not enough to a point where I would sometimes wish I could adjust some aspects of that part here and there.
Oh dear, this got quite lengthy. So I’ll just finish it with another aspect, if additional Tiers can’t be added: Tuning should impact PI. It does in GT7, it even does it in NFS Unbound, so why not in Forza?
