What do you think happened with Need For Speed? It used to be really good and then something happened with it...
It became repetitive/ other games brought similar mechanics into it. It basically became a racing game for 60 USD that each new title only brought one new gimmick/ better graphics. Personally I was not the biggest fan so I am not the best judge, but eh. Also other games incorporate fun driving in their game- I mean, c'mon, even GTA V has races. Not to mention even Nintendo gets a slice of the action, Mario Kart for godsake. It is a racing game that has major replayability due to an active online "community" (if I dare say that word). Racing games have just become irrelevant and obsolete it seems
