well i have started playing this game since yesterday so cant say very much but as the critics said that the game is short will have to see abt that,but i think the training missions r fairly big.there is a lot of micro management in this game.i wonder u will get some much time to micromanage things in the heat of the game.coz the AI does not wait for u to perform repairs to ur ship n give orders to ur carrier to fly the planes,the micro management part is good i a sense but i cant think of it as an element in the game campaign,with bombs n lots of fire power going all around u. The air combat is a bit tricky coz of the dog fights but as time passes u can perfect it.i still have to check the sub fights but i guess the overall game is worth playing.
