Back on Topic, Fans are confused regarding what GT Sport is, some say it's a Free to play, some say online only, some say prologue.
I'm quite worried the sales may suffer due to this issue, unless PD/Sony gets in detail regarding what the game truly is.
The casual millions, which obviously drives the sales, won't be having these confusions. They probably won't even know about it right now. I wouldn't worry, by the time the casuals know about it, more will be known. It's only the die hards and gaming nerds talking about it right now.
