If F1 2011 can get nominated for this (when it's just F1 2010 with some improvements) I don't see why iRacing 2.0 can't be nominated as well. And that's where my vote would go.
Are conversions & scratch builds counted separately?
What about single person builds versus team builds, will there be any distinction?
It's just the choise is SO hard & if I have only one vote I don't want to waste it....
When more realistic games were mentioned, maybe:
DIRT3 - Gymkhana is a great fun
Driver San Francisco - very good game, especially when you drive a truck more than 160 kmh through the crowded city center!
