Nobody mentioned Trackmania Turbo yet? We don't need more arcade racers, interest is so low the ones we have slip through the cracks anyway. Plus GTA5 is still very popular and offers arcade racing.
Onrush doesn't look very appealing to me yet maybe it has something. Wipeout in VR is good at least. A proper Burnout and Motorstorm would be great yet we can't have arcade racers without some kind of twist anymore. NFS seems to have finally killed itself trying to find a new hook.
Arcade racers used to be hard, yet hard is out. Without it being hard the fun has left as well.
