Personally i get the MOST enjoyment out of the game whenever some "Richtoffen" character decides he's going to single me out and shoot me down no matter what it takes. A couple of nights ago a fella decided he was going to personally put an end to my bombing raids against his sides factories. He comes after me in a P-51.. But i go up in a B-26 and i'm bombing and bugging out too fast for him to stop me from landing unharmed at my base.
So next he starts bombing the radar at four forward bases so i don't see him coming. It does him no good, because the "base under attack" warnings are telling me he's coming. I'm still evading the guy in a B-26, and by now i'm laughing so hard i can barely fly the plane. It was hysterical.
The bottom line is, there is usually a "counter" strategy to every tactic. Figure it out and have fun.
