I was getting tired of Microsoft Combat Flight Simulator 3, (CFS3) I had already done just about everything you could do on it, and I was ready for a better flight sim. I have spent many hours on CFS3 and Microsoft Flight Simulator X. I wanted a WWII combat flight sim, so I spent a lot of time looking them up on the internet and on Amazon. Essentially, I found very little about any of the sims, except for these reviews, and finally decided that the only way to find out which one was the best was to buy all of them. I had a $25 Amazon gift card, plus some extra cash, so I began to buy all the combat flight sims I could find for a reasonable price. I have heard that Combat Flight Simulator 2 Pacific Series is great, but I could not find one within my price range. I now own: Microsoft Combat Flight Simulator 1 (Europe Series) 1998, Microsoft Combat Flight Simulator 3 (Battle For Europe) 2007, Janes WWII Fighters 1998, Janes Attack Squadron 2002, and IL-2 Sturmovik (1946) 2006 (which also includes IL-2 Forgotten Battles, Ace expansion pack, and Pacific Fighters) I own many more flight sims than this, but I have found that anything from 1997 or earlier is not even worth talking about because the graphics are so primitive. I have played all these and compared them for a long time, and I have compiled all their attributes into a Pros and Cons list below. If you take the time to read this, you will know what flight sim is right for you.
