I had been playing CFS-1 (Europe) for several months before I bought this game. I run a PIII-866mhx with 256MB RAM and a GE Force card with 64MB of video ram. No problems with hardware. The gameplay I've found to be more challenging than CFS-1 (the enemy planes seem smaller and much harder to hit). The cockpit renderings are fantastic, and the air-to-air combat scenery is great also. My beef with the game is twofold: air-to ground action, a big component in the Pacific campaign, is really weak (lousy ground graphics), and from an historical perspective the game misses some critical campaign pieces (most notably Iwo Jima & Okinawa). Overall a lot of fun, especially carrier landings.
