It does lean a little more towards arcade rather than sim.
But my god that vintage Bentley from last seasons challenges definitely does not handle like its on rails once it's upgraded
The menus are super confusing to start with, and there's no real guidance.
I found myself having to Google a few times when a bit lost.
And some of the challenges are really badly worded and it takes a minute to figure out for example if your supposed to be doing the challenge on a road circuit or A to B sprint race.
Another issue is it makes supercars very accessible, which I suppose is a good in a sense that you don't have to really grind too much, but I'd have liked to see a licence system so you can only drive catagory D cars to start with and work your way up.
I do enjoy it though, mostly play horizon tour now and the seasonal challenges as I've done all the regular races..
I suspect if you play co-op and or in convoys that adds an extra element of fun but I've not really done much of that side of it yet.
