Bunch of screenshots of Fable have been uploaded to Steam, far too much post-process (thankfully I'm playing on PC) but the game is gorgeous in my opinion:
What Forza Horizon 6 looks like is exactly like Forza Horizon 5. From art direction to rendering, there's minimal difference. Based on the actual gameplay in the trailer, it looks nothing like this hyper real artstyle.
The bottom picture looks way more appealing to me. I've never been a fan of that blurred early-2000s pre-rendered cinematic vaseline look with excessive post-processing.
