Hmm, looks like I may get Race07 after all. One question- Are the add-on tracks supported in both the retail and the Steam versions?
EDIT:- Apparently you can add your own tracks/skins etc in the Steam version...
I think I am going to get RACE07 instead of rFactor. It will let me import tracks, has a good selection of cars and seems to be a much more 'solid' purchase out of the box. After all, I want to spend my time racing, not installing a plethora of addons. Also, the selection of cars should keep me happy for a while.
Feel free to tell me off if you think I have made the wrong decision!
