These two pics are the beginning of a AOP2 game interface.
In these two pics you will have to look very hard but there is a difference between the two. ( forget the white waterline at the ships hulls as that's not what I'm referring to because there is a slight change in the two pics. )
Hint: It has something to do with fish.
This interface also changes to evening with the ships lights aglow, rain, sunny daylight. Its something different and nice to look at before a game.
