Its worth getting imo I've been playing it since release. But bare in mind the physic is quite...horrible

game levelling is pretty fast, just finish all the main missions and you will hit lvl 50.

dont need to spend much time farming item in challenges, as when you are around 40-50 you will unlock platinum medals which has all the RNG, then u only farm

aside, they give 110,000 in-game cash (credit) when you hit lvl 10, i think it applied to all limited/gold edition, not sure if standard edition receives too. You can spend them on upgrading or buying perks, or simply saving them till 50 and then use them on the car you realy like, its really cool they give 110,000 which is alot imo.
