There has been quite a few threads about bugs, glitches, and graphical errors, but nothing on the sound. This isn't a bug per say, but I thought I would mention it. The ambient sound is pretty quiet (I know it's the vacuum of space, but still), and I don't have desktop speakers, just built-in speakers on my Asus monitor. I have to turn my volume almost all the way up to hear the explosion sound effects (70 out of 100).
This is similar to what I experience when playing Watch Dogs. My sound needs to be around 75-80 to hear the game properly. Of course, this could just be because I don't have speakers, which is most likely the case. Oddly enough, Universe Sandbox 2 and Watch Dogs are the only games out of 40+ I have that require me to turn the volume way up to hear it.
Most of the time, I have it between 25 and 30, and can hear those other games just fine. I am guessing the sound is going to be tweaked throughout US2's development, so it could change I suppose.
In short, will the sound change at some point so you don't need to turn the volume up so high (at least for my case)?
