I have been a huge fan of Simbin from the beginning. I own GTR, GTR2, GT Legends, RACE 07, and a few other titles. I have also bought copies of a few of the titles to friends to introduce them to sim racing. However, as huge of a fan of Simbin that I am, I cannot justify purchasing one more car or one more track without some confirmation from Simbin about multiplayer being unlocked soon. After scouring the Internet, the only evidence I can find about the intention to offer multiplayer is a greyed out "multiplayer" option on the menu screen.
My sim racing investment is waiting for Raceroom Race Experience, GTR3 (which could be vaporware), Project CARS, Asseto Corsa, or RFactor 2 to demonstrate to me that their product offers the most realistic sim racing with stellar graphics, real physics, dynamic weather and day/night cycles, historic and real tracks, and lag-free multiplayer. Then and only then will I throw all my money to the victor.
