As someone who has been playing the crew franchise for multiple years, the Crew Motorfest has so far been a let down to the franchise. They have tries too hard to make their game like a cross of NFS and Forza Horizon, that the game doesn't have it's own identity anymore. PvP in Crew 2 was fun and was all about the better driver, where as the crew motorfest is a cluster of people not knowing how to drive and just ramming.
For the endgame of Crew Motorfest, there is nothing exciting. There are hardly no races (unlike the Crew 2), the map is too small. The summit is has gotten worse as so far there is an exclusive car once every month, maxing it only worth while to play once a week/month (depending on rewards).
On the positive, the handling of feels nice, but is too different to it's predecessor.
Overall, the game was fun for the first 10 hours, but now, I still spend more time on the Crew 2, due to its better PvP design.
To make the game more fun, they need to add another grand race playlist but with less people a race and with a ranked system, so you can get matched up against people at your own skill level.
