The turbo just added VR experiences on to the normal game. It's crazy the way it makes you squeeze your stomach playing the VR part going through a loop like your on a roller-coaster.
But, I have also been playing the regular online game that anyone can play trying to get my rank up for TN, USA and the world. Really alot of fun if you like racing. I wouldn't worry about not having VR, the normal game is worth its price.
