Honestly Nascar Heat 5 is pretty much just a reskin of nascar heat 4 and its more expensive theres like 2 new tracks and some new drivers but other than that its the same.
I did the sound for NASCAR Heat 4 and it seems they didn't even fix the audio bugs from 4, in 5. From what I've heard they simply reused my audio.. I wonder if I got a credit?
I dont have it but I'll see if I can check the credits --- Post updated --- Cant find any way to view em
