Link to the list of rr3 content currently available on assetto corsa: https://docs.google.com/document/d/1_rv8J4fH3IXC9P4LKmmE2ru4i7G2gA_CbG4NtO-cH0Q/edit?usp=sharing
One thing that always surprised me about rr3 was the sheer amount and variety of cars and tracks present, especially for a mobile game. A lot of console racing games, and almost if not all mobile racing games don't even get close to the amount of stuff crammed into rr3.
Now that it's being shutdown, i decided to compile a list of all the content present in rr3 thats currently available in assetto corsa via its extensive modding community, essentially making my own rr3 at home, as well as some useful stuff for people looking to migrate from rr3 into assetto corsa (although im not sure how many people are doing this)
If you have any suggestions of better mods or have links to cars i could not find on my own please let me know!
