Like I posted above Tore, this is how the original IL-2 started out. If you didn't play it, then to explain, it was only germans and russians, an IL-2, russian "fighter" and german "fighter" campaign, and that was it. You couldn't choose what planes to fly, all combat was pre scripted, all planes you'd use were pre-scripted, and, not counting version types, there were only 12 flyable planes. So this game is going the same route.
On the topic of the "epilectic" issue. I read through the forums, and it looks like the devs know about it, and are fighting to fix it "within days, not weeks." So hopefully, it'll be fixed soon.... The main thing is that it apparently does not support SLI.
