VHR is very, very impressive. Gorgeous graphics. nice physics, although a bit looser than I think is realistic. But here's the rub: The A.I. is just as fast at either 75% or 95%. I swear, I tested the A.I. "Difficulty" slider, starting at 95% in a race on the same track, progressively moving the slider down 2-3 points for each race. I only needed a couple of laps to tell there was no noticeable change in A.I. ability/speed until I got to the mid-70s, and the change I did see was minimal. Other rFactor mods I've tried introduce much more dramatic change from 95% to 90% to 85%. Ditto standalone racing sims like F1C, NASCAR Racing 2003 Season, GTR2, etc. Not VHR. In fact the difference between 70% - the rock bottom lowest you can move the Difficulty slide - and 95% was only slight.

VHR Stock Car RAcing could be an awesome mod if the developers could make the A.I. significantly slower at 70% compared to 95% or 100%. Before anyone says "rFactor mods are all about multiplayer," you should know that VHR Stock Car Racing not only has a complete single player mode, it comes with a complete offline VHR Racins SEASON. This is a good thing, because a lot sim gamers racing predominately offline. They just need to fix the A.I. Difficulty, so that moving the slider left or right yields significant speed changes, enabling offline sim racers to find that sweet spot that works best for them.
