Hey guys, since Gran Turismo Sport doesn't have a solid career, I am looking forward to the Arcade mode to setup custom races and earn credits, etc. However, in the demo, there are only 4 tracks I believe. How do I unlock new tracks both in the demo and full game? Is it difficult to unlock new tracks? I believe this is done by gaining experience but there is no way to tell when or at what level new tracks will be unlocked from what I've seen so far. Thanks for the help!
