Battlehawks 1942 was the first of three World War 2 flight simulator games LucasArts decided to make during the late 80s early 90s. It was based around the Pacific air war theatre, and consisted of 4 pivotal naval battles including: The Battle of the Coral Sea, The Battle of Midway, The Battle of the Eastern Solomons, and The Battle of the Santa Cruz Islands. In all four battles, the player could either play on the US or Japanese side giving some nice re-playability.
The game was made using a sprite-based model, allowing you to fly in a real 3D environment. Unfortunately, looking at the graphics today, they haven't really held up, giving a very clunky and cluttered feeling while flying about. Fortunately the actual game-play was very accurate, as they managed to capture strengths and weaknesses to many planes of that era, giving you as real an experience as you could possibly get during its release.
Bottom line: if you are one of those people that cannot get enough of World War 2 or flight simulators this game is a must to play.
