RF2 isn't finished yet, same as pCars and such.
Indeed time will tell what we get. No doubt they'll be good.
For now there's not many that can run it at all.
For now, GTL (>R2) will do fine, as we can finally run it to the max (can we? online nightraces? never seen them...)
...plus it is mod-able so there is always the content that you're liking.
(I can't be bothered if a game doesn't have classic cars, or at least Minis).
BTW weather indeed, but all there is in most is rain, more or less.
Where's the snow, hail, icing, etcetera? As Donington should have rain,
many tracks should have ice and snow.
