i am a regular player of rF,mainly solo mods... and my biggest complain is about AI ....very good in qualifying but when it come to race they r completely dumb !!! my main concern(a common concern in my opinion) about a racing SIM is to be the most realistic possible,weather,wheather effects on track(like dry lines and raining only in some part of a track),AI(agressivity,TO techniques),tyres behavior(tyres track interactions,temp effects....) physics in rF1 are very good so they just need a little tweak... all this blah blah to say ...why dont you think of recruiting "Geoff Crammond" or atleast rebuy GP4 license and inspire from geoff's work to improve rF2 realism ???
