To be frank, even as an arcade racer fan since as long as I can remember, the gymkhana and Ken Block stuff from Dirt is so unappealing. And I love the Dirt Rally games as sims, they go straight to the point and are such a joy for rally fans. Bless them. But the main series, since they transitioned from Colin's name, it's totally lost.
Same with Grid, really. It's not an arcade, but it's not a sim either. GT Sport with driving helps is far more enjoyable. Horizon games just by looking at the spectacle, the colour palette and how you can drift overt brick walls says it all about what to expect. And they sell gangbusters so arcade is definitely not dead.
Very few selected games do the middle ground well, Driveclub was probably the last.
