Yeah I gave up sims for quite a while. Aces of the Pacific and Aces Over Europe and then Strike Eagle III and then I sort of stopped. Everything got too complicated for me to really enjoy...so I stayed away.
Then something got me interested in CFS3 and WWII air combat again so I watched that game get developed. Turned out it was a bomb so I avoided it and broke down and bought Forgotten Battles instead (the old IL2 demo was a blast!). Its still somewhat complicated but there are no fire modes, radar mode types, setting silly little nitpick things....you have a crosshair, an engine, and a trigger and when you shoot things blow up good

Its obviously more subtle than that but I've managed to slowly work my way up using more complex engine settings (and really its not THAT much more complex) and things are good!
