So here is my thought. Dram has discussed in the past reworking Human eco to havea ~300m freighter fly in from orbit and pick up Balterium as the new means of human eco working.
So, if we humans have a freighter in orbit, can we have cameras or radars attached to said freighter?
The gameplay mechanic/benefit of this is for intel purposes. Say you are RTS/COM role. You want intel on a piece of the map. Maybe you want to find resources, spot enemy units/defenses, etc. So you spend some currency and get to view that part of the map for like a minute. It does not increase build range at all, but you get to see what's going on far away from your own borders, courtesy of your orbital freighter/assets/cameras.
The same can apply to the players/FPS role. They can spend their personal resources to obtain intel/view over a map area that they cannot see. But the view that can be obtained for an FPS player is much smaller than a COM, maybe only 25% of what a COM can request.
So COM can spend more/less/same amount as an FPS but can see 4x what an FPS can view. Your viewing ability is limited to a certain amount of time to keep the game balanced. The cost of purchase should be expensive enough that its not something that should be used excessively. And you should only be able to request a special view of 1 part of the map at a time. Perhaps a "cool down" mechanic can be implemented to make players/teams go 2 minutes without any intel vs only being able to purchase 1 minute chunks of intel.
I would not extend this mechanic to aliens. They quickly obtain intel early game with lots of spread out, cheap units.
Offer your thoughts. Good, bad, meh, or suggest tweaks to the idea.
