GTR Evo was the first racing sim I ever got. The next one was GTR2. Then came GPL, rfactor, F1 Challenge, NR2003, RBR, and many more.
Whenever I go back to these Simbin sims, I am blown away by their quality - Simbin did amazing work back then!
I think it's funny when people think of GTR Evo as a game, when it was really DLC for RACE 07 (if you used it's launcher you got a different interface though)
