I just played through Blue Planet just now for the first time. The campaign was great
however I have a little problem I would like to mention about the special effects.
When a bomb or big explosion occurs in front of you, your entire screen whites out for a few seconds, during which time you cannot see anything. I played this and found that in most of the missions there are a lot of bombs going off at the same time, or in close proximity to each other. This caused my screen to white out for many seconds at a time to the point where I take my hand off my mouse and sit there until it all comes back. I might be in the middle of a dogfight and have to break off my attack because I cannot see anything.
I think this effect is good and makes sense. However you should be blinded by bombs that blow up in your face at most 300 meters away as a punishment for looking at the explosion at such close proximity, instead of a little bomb blowing up 1500 meters in the distance whiting your screen out. I found that this effect, although neat at the beginning, became a nuisance later on in the game when more stuff was going on in the background.
Perhaps you could update the effect to white out the screen only for big capitol ships blowing up or for bombs blowing up right in front of your face.
Other than that, Blue Planet was a great experience. Thank You!
