Wouldn't it make sense after being on Mars for a while, a rocket pad would be made? Maybe have a refinery directly attached that refuels the rocket? Plus I think it would look a lot cleaner than a black burnt mark on the ground.
As i seen in video's, the rocket landing and starting makes nearby buildings dirty. maybe it would be a bonus, if the landing pad is somehow walled and prevent the spreading dirtyness of other buildings. ^-^
I've been using the terrain from depleted concrete deposits, and surrounding it with concrete storage to make walls. Then using those as landing pads.
Would definitely subscribe to a mod that implemented actual launch pads though. Would also be nice to make roads, even if it was just visual.
