These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Crowning Music of Awesome: Some straight from Vega Strike. Some tracks include Void Sensor and Revenger 34, along some others, the House Zalek theme, House Sirius theme and it's remix. And lastly, Machina for the menu screen.
Peace6 gives that feel of lonelyness and the lack of Sol and Earth...
+1 on the House Za'lek theme. It just makes you feel like you're in an advanced society far ahead of the others. The Za'lek's secondary theme is also a treat. The person who made these songs has contributed some of Naev's best music.
