Fantastic scenarios! I liked both the routes and vehicle selection.
My only complaint (not worth knocking to down to 4 stars though) is that the checkpoints on the Long rally scenario are way too narrow IMO. I'd like to have them set wide enough to where I could either hug the apex super tight, or be at the other edge of the pavement, and have them both count. Also, I couldn't find the dirt jumps scenario :(
