hey guys i have the original Il2 sturmovik and it only has 32 planes, along with that i have pacific fighters with no expansions and im wondering if theres any place where i can get ALL the previous game updates like from version 1.0 which is the ones i have to version 4.08 because i want new planes but i don't think any of those will work because i only have the 1st version so please help. Also i might get Il2 1946 but can someone explain what IL2 1946 comes with? it saids that it comes with pacific fighters and Il2 and all the previous expansions including forgotten battles. Is that correct because i really want to get the most up to date game, but also have them merged. The original Il2 lacks a lot . need update! :x
