As much as I want to like this game, personally, it seems to have too many holes and missing/coming soon features for a 2015 release.
The game does the racing element rather well in my opinion, HOWEVER, it forgot about "making love" to the player and other elements which make up a track event.
It is a very cold, sterile experience at times, kind of like paying for sex. Sure, the job may get done but it is just not the same.
I have not played AC, but what I can gather, neither AC or pCARS are what they could be yet although both are "Gold".
Am trying Raceroom Experience, which although has its own shortfalls, is not "Gold" and is showing promise.
For the time being, I have gone back to GT legends.
It is more "feature complete" than anything else on the market at the moment.
I may even consider rFactor 2 another go, seems to be getting less love in the rush for these "new" titles but these new titles are lacking in needed areas.
