A decent arcade flight sim that does what it's suppose to: Entertain!!
Graphics: Surprisingly good for a budget game and detailed especially the water and sky. Land could use more detail though.
Replay value: Good. You can play each mission over especially if you failed it and simply moved on but you want to retry it after finishing the game. In this catagory it excels because you can play missions again to receive higher scores, enemy kills or just want to play the mission a second time though.
Overall: AOPH is a fun, arcade combat flight simulator to play and I recommend it if you like the Pacific War theater or just want something to play that is fun and not serious. Attack on Pearl Harbor will surely please you.
