Only two games i know has this ability to have the base and units left where you left, built em. (non-op2 game, and few mission in op2-renegades.)
---This is an Campaign related idea---
On the start of the game (or wherever) you build a magnificent base that could hold lava, (blight) enemy for a long time... and you lose it when you play the next mission.
The missions of TFC are on one planet.
So, when your base is built and you finish a mission, the next mission you start, your base will stay put. Every building, wall, defence, unit, ores, trucks will stay where they are.
So every mission, you expand your base (when you have a home mission (collect ores, gather troops, send something...) your base will look like that when you play your next mission.
When playing an away mission (relocating base, attacking base, collecting debries, ores,) the base will stay in the same shape how you left it.
This is a question for all:[/size]
Dont' you hate when you have a load of ores, food, defences, people, and when you finish a mission, it's all gone?!
I hate when that happens in op2. :'(
