The part about the "built from the ground up"-game being scrapped after 3-4 years of development, and the game we got being hastily put together after that, sounds like just another conspiracy theory to me. There's been play testing with the community going on since early 2021. I imagine that would've been hard to do if everything was suddenly scrapped.
Slthree states that "the game doesn't feel like it's been six years in development". Well, if he'd just taken time to do a simple Google search he'd found out that early production started March 2019. So no, it has indeed not been in development for 6 years.
Let's not forget that Covid arrived just months after the work on FM'23 had started. Chris Esaki himself described 2020-2021 as the "Dark Souls of game development". I imagine everything was harder and took way more time when everyone was working from home. I'm not defending Turn 10, but this is an explanation at least.
I think
@nukleabomb theory sounds more likely. After re-working the physics and modifying the game engine (going from baked lighting to real time etc), there wasn't enough time to update some reused assets like old car models for example.
This is just my semi-(un)educated guesses. What do you think
@PJTierney? You have way more knowledge about this sort of thing.
