In TA, though, the wireframe of the structure appears, glowing. Eventually the texture maps fill in, and the unit or building is completed. Few vehicles have a visual range that exceeds their weapon range. It is disappointing that there is no vehicle with a large visual sighting distance. Even the planes lack a wide sight base, which was rather confusing to me, that scout planes would be able to see little more than any other unit.
Units interfere with each other.
This is because of the true 3D nature of the game and units. It seems like a good idea, and it is. However, it leads to a few problems. What happens is that you can never tell if one unit can manage to squeeze through the space between two others. Units block each other more in TA than in any other RTS game I've played, because units are not required to travel through and stop in the center of predefined blocks.
