Just bought on Steam sale....held off as I had versions in other sims, but I must say I am enjoying this immensely. The 1975 circuit brings back memories of Grand Prix Legends and the 1991 of Grand Prix 3.......only so much better. Perfect match with all the vintage F1's in the AMS2 stable. The modern version is great too as are the short versions. Getting a nice selection of vintage tracks now.....waiting for the original Spa!!!!!!!Thanks for all the great work.
