For sim racing to be recognized as a sport a lot need to happen. First off one needs to decide whether it is virtual form of motorsports or gaming tournament with racing game. Most LFS racing events seem, feel and sound like racing game events, even if some more serious than others.
Like ASUS 200 instead of Ford virtual 200. There is a huge difference how you look at these, one is something that takes a lot of skill and in its own way is fun and very challenging. Other is serious, structured and on some ways maybe bit more dry while the other one is much more fun orientated. The way the crowd sees the event is totally different when you are watching a game instead of virtual racing event.
The fact that the driver is some spotty nerd living with his parents on his late 30s doesn't take anything away from a virtual racing event but that same spotty nerd is the prime prototype of a pro gamer.
It is a bit unclear wether the iracing want the pro racers or the pro gamers. LFS and nkpro are clear cases with their approach
Another aspect is internet. If some serious racing events were arranged so that everyone is in the same place (=LAN event), had a nice 20 or 40 401 motion sims and high-tech PCs. A true F1 of racing sim events. If the same event was arranged via internet it would not rank as high because it is automatically seen as game.
I have huge doubts wether iracing or anyone can make simracing big but it is good to see that some are trying. In the 60s and 70s people would say you're nuts if you said something abiout mobile telephones. Maybe it is same thing with sim racing. Before internet connections and online racing the racing sim fans didn't really like internet racing but once they tried it they couldn't live without. Maybe there is another step to take, I just can't see how it could be done and with what but maybe the step is not really big for sim racers, maybe the step is for the viewers and those who see simracing just as gaming?
