RR3 still has one of the best graphics ever, even tho it's so old. This may sound weird but I like RR3's graphics more than Asphalt 9's. Asphalt 9 graphics feels a bit too flashy to me, and RR3 feels very natural. AR and CSR also have good graphics.
RR3 anyday of the week, Straight off the line drag racing in games gets to a point where it's just not fun anyone but track racing? That'll never happen with it. IF CSR maybe tries to focus on adding better vehicle physic, tracks, and the ability to turn and actually race through tracks, it would gain an even bigger audience. Their car models are already mindblowing!
