As a long time Simbin fan I gave RaceRoom multiple chances (early builds were very floaty and unsatisfying, as I'm sure everyone remembers) but clearly those of us willing to do that and willing to spend rather a lot of money on the drip fed content are a small minority.
Picked R3E after march 16' update so i haven't been on the ride since day 1.
Still it has got better and better with every update since then. (Hopefully you are still playing until today )
I can't wait for the BMW M6 GT3
