Il2 Sturmovik originally came out in 2001. Blimey, where did those years go!
I hope they fix the only really annoying bug in IL2 for me which was always having your wingmen break formation and race off after an invisible enemy.
Alright...how do you know the Blenheim hasn't run out of fuel and is gliding down to a watery end ? Eh ? EH ??
Here's a couple of IL2 screenies I did for a screenshot competition way back when. No special effects or Photo-shopping involved; these are as they appeared in the game.
