So basically 2014 with slightly upgraded graphics and less features. They could have released this in place of 2014. But hey, at least we get pre-race grid scenes and podiums instead of a proper career mode this time. I guess those kind of groundbreaking additions take 4-5 years to implement as they were more occupied with removing things each time.
I believe this particular gameplay is showing of the '2014 season' mode and not the 2015 season just to clarify. *This is according to a couple of YouTube videos and comments made. Correct me if I am wrong.
