I've hardly played it (Steam reckons I've got about 5 hours total over the past 2 years or however long it's been). From what I've seen in the forums, I like the push for more innovation with league-admin and broadcasting features. The few cars I've tried feel good on the gamepad (I haven't used my wheel in ages), I like the huge number of tracks, and the interface seems more polished.
With regards to consoles, it seems that the worst console in the current generation dictates what all other consoles are allowed to do in terms of opponents, etc. There is no livery editor simply because having customised liveries would mean less cars can be on the track (system memory limitations). PC doesn't have a livery editor either to be sure, it's just swapping some game files around (essentially modding). Many slower PC's would probably struggle to fill every grid place as well (slow FPS), so I think it's nice they don't limit everyone with newer PC's. That's like complaining that the console version can't do VR or triple screen imo. Of course the grid size entirely depends on the selected track and number of pit bays as well. If you select a full grid then tracks like Cadwell Park disappear (limited to 31 cars from memory).
It'll be interesting to see (1) if it releases on time, and (2) how many bugs slip through and what the public reaction is. GT Sport and FM7 will be releasing about the same time, and probably have been developed with much bigger budgets. I'm not sure if I'll pick either up in a hurry since I'm just not gaming much at all these days.
