I am just very satisfied with my version of AC, it is the best racing game I ever had the chance to play on my rig.
It looks great in my VR goggles, it feel great on my DD wheel and load cell brake, it delightfully vibrate with my tactile, I have more content that I can use in 2 life time.
Like for example, your Sol weather system, to me is like that:
AC Evo weather is like this in comparison:
I just enjoy the great game that I have, with full control of great weather options, working flawlessly.
My hobby, is enjoying pretend racing on my rig, not tinkering endlessly with minute details, wondering if the sky should be an other tint of blue or should the clouds have a different perspective.
There is one aspect that I would gladly spend money on. An app that would allow me to add movement to the driver with clicks of the mouse, from inside the game. We know, from some great mod car we have, like from F40 LM_Lover, that driver animation in AC can be "perfect", better than any other game, shifting the right gear, pressing the right button on the wheel, feet pressing the right pedals, etc.... It is a VR thing and most are probably not interested, but since I already have everything else, that, to me, would be a valuable development.
So, does pure do a better version of the Sistine chapel ceiling, I have no doubt, but the one I have now is already good enough for me.
