what do I need to play 1946?

[kpii]

I saw some youtube videos of IL2 and it looks great. I haven't played a flight sim since Aces of the Pacific in 1992.

I want to fly P-80's, ME-262's, GO229s, Shindens & Kikkas against B29's. IL2 1946 looks like this is possible.

What do I need to do this? do I need to by the original IL2 and then the 1946 expansion? Where do I buy them?

What kind of hardware do I need to play?

Thanks!!
