4 is amazing I agreed with almost every point except the car sounds part. Sure in h5 most cars in the same family sound the same but h4 the sounds are very electronic and in h5 cars sounds a little more beefy and match the rpm’s
The best Forza map would be the City of FH 4, the Forrest and beach of FH 3 and the desert/desolate parts and mountain of FH5. But generally, FH3 had the best map so far, dunno why but I played FH3/4 and 5 and 3 still remains my favourite.
