Titanomachina variation

What if we took all the habitats off the board? And we go back to starting from an empty board? The question, of course, being how to put them back on the board... 

The easiest way is using sensors. It leaves the game as is. In a 9-round game a single-sensor system Titan can place 16 habitat buildings in towers of 8. At best. A three-sensor system Titan can place 22 in the same 9-round game. 

There is also the issue about perverse incentives for putting buildings on the board. On the other hand, destroying line-of-sight blocking terrain has the effect of exposing oneself to retaliatory fire. It also wastes an attack on a building. Players aren't restricted to only placing their own habitat blocks though.

If we did this, the numbers on the Titan dashboard cards could represent a starting score. 

Originally the notion was that the Titans would be able to place habitat blocks as they move. I don't know how to make that work. It was intended to give an empty board something of a fog of war effect without clumsy extra counters.
