2 lap races, little perfect corner markers, count downs at race start instead of lights, lots of motion blur, rev lights up for gear cahgnges and career progress through various cars based on points obtained in races not on finishes. It is a need for speed hybrid game by the looks of things and not a project cars game, at least the career looks nothing like PC2's career, none of this is looking very sim like.
Multiplayer with scheduled races with matchmaking and safety rating, custom lobbies and the usual pickup.
This is not yet looking or sounding like a PC3 game, it looks like a NFS game by its features.
