I think that would be the best option Ron..
iRacing is far too expensive to ever consider even if they did manage to improve their physics. You'd reduce your pool of drivers enormously in my opinion. If rF1 is only choice next year we shouldn't worry about it too much. Lets not forget we've been using this for a while and its still very enjoyable. Drivers just need to remain patient and eventually we'll have the best option possible. Otherwise we could end up moving to a simulator that isnt very good. Good things come to those who wait.
rFactor 2 and AC would be both a good choice, but the problem is that both wouldn't be ready if we start the new season. So we should rather discuss which mod we will use next year because iRacing is no alternative.
