I've been playing the IL*2 Demo for about a day now and if you have a the slightest need to dogfight over a WW2 theater of war, this is your game.
I advise people to download the demo and give a go ( the demo on the PS3 has 3 full missions to tackle and 2 difficulty levels each to unlock! )
if your still on the fence, just wait for a used copy. I can see how younger gamers ( the Halo, ADD, quick fix generation ) will probably trade this game in quickly for something a little more flashy.
here's a video review from 1up.com to give a taste of whats in the box.
