I have been sim racing since 98, and for some odd reason, I never tried R3E until several months ago. After 170 quick hours of racing single player championships with AAI, I must say this is the best offline racing I have ever witnessed. From fighting to hold onto a position, to performing a pass anywhere if I'm not fast enough, all while keeping it clean, just blows my mind. I've never seen anything like it, and I can't get enough of it. I absolutely love the AAI as well, as fooling with obtaining the proper difficulty has always been a pain-point for me when going from track-to-track in other sims, and this takes care of it! I've been reading the forums, but this is my first post. My advice for the folks looking to train the AI is to just set the difficulty to Adaptive and race! You will win some, you'll lose some, and before long every race will be extremely competitive, and when you win, it will feel deserving. For those that enjoy offline racing, there is nothing that compares to R3E, and yes that includes RF2, AMS2, and the other sims that many folks claim to have the best AI. Sector3, please don't break what is fixed. I don't know how you have accomplished what no one else has, but I'd love to have some insight as to how it came to be... it would be book-worthy, in my opinion. Keep up the good work... I'll be supporting you with any and all content you release in the future.
