I have to say, racing the F1 Karts is WAY better offline than online last night. The AI actually with those things is very impressive IMO by rF2 standards, nearly approaching Papyrus levels, that's a pretty big compliment in my book.
F1 Karts on the Medium layout is amazing, you can really feel the physics work in the 90 degree left / long right / fast double left section. Just boom - the feeling of on the edge, the throttle control, the steering, the FFB working - fan. freaking. tastic. Easily, hands down, 1000000% the best experience in rF2. It makes a great case for either buying a servo wheel or a real kart, decisions! LOL
I've been rather outspoken on not necessarily being an rF2 fan around here, but this... this... THIS is rFactor 2. The UI, the HUD, The driving, the track - this is how you do it ISI, now keep it up!
Also, are Superkarts planned? They'd be great for where rF2 currently is track wise as they fit some of the smaller tracks great. Mores, Croft, Symmons Plain, Poznan, and Putnam Park (imagine the draft battles online!) would be fantastic with them!
