Already gave it a shot, but gotta say its not my cup of tea but maybe i'll give it another chance if timing with event fits ;)
From my experience I have much more fun playing this with friends than solo. I was trying to play singleplayer in grid2 and autosport, but no luck. Multi however...
Maybe this clip will convince someone to play this game :D
If someone did not manage to get a grid, he can still buy it on g2a. People are reselling these keys for 0.5€ atm.
