If the game was solely built for me, it wouldn't have road cars either because I like racecars. But it's bigger than that. Some people like driving the Ford GT. Others the GTE. Some like driving the Honda Civic. I'd rather have a race car. But the game isn't just for me. It's for you guys too and sometimes I actually like having a small drive of the Honda Civic. It's a surprisingly fun car to drive and I wouldn't know that if there was solely racecars in game.If others had their way, players like him and me who enjoy driving roadcars should just "go play Forza or Gran Turismo," leaving PCARS for the crowd who only want racecars in their sim and feel like roadcars don't belong.
Somebody else having something is not an excuse for us to not have it. If anything, it's a motivation to have what they have because some people like what they have. You take everything surrounding GT's livery editor and put it into every racing game, I'd be happy with it and I'd have a lot of fun making my amateur liveries and looking around at what talented people can do.
