I'm pretty sure it would work, the only thing is that it'll have to be good, and not another case of "i want to, but i can't", which has left a negative impact on other companies who've tried/ are trying, it'll be a very difficult task to please the existing AG audience whilst also bringing in new people, especially pleasing the existing ones, you see it a lot on here, lots of people wanting the physics to be similar to the way they are in HD, while others want it more like the classics, same problem with track design, some want flat and realistic, others curvy bendy high and low

I'm pretty sure you could pull it off, TTR WT looks great, but i'm not sure about early access, not unless the early access has the core physics finished (handling, gravity, air time, acceleration, speed, collisions) because inteoducing sloppy physics in a Ag racig game is a big let down, which you really don't need as a first impression (first impression is eeeeeverything!!)

But i do have faith in your studio ^^
