I'm a il2 player from china,I know some circumstance about this.
The guy called @6 who devolped IL2:SONIC AGE is a trustworthy and respectable simulator in china. Perhaps Oleg Maddox knows SONIC AGE more than most people here.In fact ,@6 once communicated with Oleg during the devolopment of SA.
I can also provide some other information. In 2005,@6 orgnized the first ICAS( international cyber air sports) ,which is a international competion for il2 simulator. Players from 10+ countries attended ICAS including Russian players, and Oleg was invited as a special guest to come to china.It's hard to belive that @6 stole Oleg‘s il2 and sold it. In fact SA is free downloading.
those rumour about SA comes from some chines players , they are hostile to @6 and SA for some reasons,so they distort the facts.They should be totally ashamed of thier behavior.
