I have to admit that I'm a flight sim novice that only really dips his toe into these sorts of games. However I bought the first game and now, having got a system that will run this have bought this one.
This game takes place on the eastern front of World War 2 where you can take command of a huge variety of planes from the various warring powers. This is not only from the USSR and Germany but also Hungary, Finland and the USA (to do with battles in 1945 I think). Players can command fighters or bombers on a variety of tasks from ground attack, escort duties or air to air combat. This can be on single missions, campaigns or online gaming.
The first thing that strikes me is the enormous depth of the game in it's realism, research and most strikingly of all the downright beautiful graphics. Admittedly I'm running this on a 2.8 ghz processor, 512 Megs memory and a 64mbs graphics card so I am able to ramp up the detail but believe me it's worth it.
As for the gameplay, it's superb with wheeling dogfights and low level chases against the enemy. Various modes such as the campaign side have been revamped from il2 to increase the lifetime of the game and you definately get the feeling that you're really taking part in things.
This is one of the games that you do need to work on but I think it'll be well worth it on the enjoyment side of things.
