Ride 4 was complete and utter rubbish IMHO and I guess Ride 5 will be more of the same old cheap thrill rubbish.
Back in the day Ride 3 and earlier games were playable and kinda fun. Online too ... But for Ride 4 the physics were nonsense at latest patch version and by time I bought it as cheap as chips on a sale I could see that.
The whole grind too before you were allowed to access the full game you owned outright by stupidly slow lapping penaltys was dysfunctional game design IMHO, they would do well not to repeat that stunt in Ride 5 if they want new blood onboard.
Some of us here have actually rode modern Superbikes and have something to compare to, raced on real race tracks too, Knockhill here.
If Knockhill creeps into a track list for Ride 5 ... then I might be interest though ... but I doubt it, there will be nothing really new with Ride 5 I betcha.
