You cannot adjust the display resolution, something I wished for on several occasions when I needed to see more of the map at once. One area that doesn't work that well graphically is how Dark Reign displays elevation. I found it very difficult to see these elevation cues. Total Annihilation , which also models elevation, uses a much easier to see scheme for elevation. I wished for something similar here.
Sound effects are nice.
Explosions and the fire of the plasma turrets are especially well done. It's also pretty simple to determine what units are firing based on the sound effects, something that can be quite handy. It is printed on extremely high quality paper in rich, luscious color. It contains all of the information you need on units, the story, and the mechanics of play. Also included is an online version of the manual in help format for those that prefer it.
