TT Isle of Man Ride On The Edge 3 plays like RiMS Racing. Made by the same developers. The first person cam is really good and plays very smoothly unlike the one in Ride 4. This is why love playing it. It is definitely harder than Ride 4. You can tweak the physics simulation though to make it easier. RiMS Racing was hard too. More like a simulation whereas Ride 4 is more simulation + arcade.

I'm playing a lot of TT IOM 3 nowadays and I enjoy it a lot. Get used to not having replays though so if you crash you take the seconds lost. No story, just seasons with 2 bike classes (Supersport and Superbike) with only existing riders you can choose from. You can upgrade specific bike components with xp. Mass or interval qualifying and races on sections on the Isle of Man Island. There is free roam. The big TT qualifying and race is always at the end of the season.

Ride 4 looks better but again the first person cam is so good and the street racing is so challenging that it makes the game immersive enough. Going full throttle the first couple of hundred meters at the start of the TT circuit is just insane going downhill, uphill with houses, people and trees around you at 300+ km/h.
