It's just like the first version except the Germans have been replaced by the Japanese. Carrier take offs and landings are introduced. CFS1 installed for about 257mb on the hard drive, CFS2 is a 2 disk job that wants about 850mb. The easy mode in the campaigns is a lot easier than CFS1. Whilst its not bad I don't think its worth the money if you already have CFS1...put it on your list for your next visit to Hong Kong.
