Sorry but didin't have the time to look into the various addons, but i have two sugestions.
One of things i hate in VGAP is having lots of resources in one part of the empire very little on the other. So an addon that
could beam across would be wonderful... humm i think TELEPORT does that right?
The other, would be a way to give the birdmen some advantage in money
. Everyone knows they are weak on that respect... and don't start another birdmen is weak thread please.
Don't know if sphere is a good choice though. There's that thing that Matthias pulled on one of his games. It was with Donovan? Can't remember very well...
Asteroid is good, but they must appear. In PG1 i haven't seen any. On Pg2 there was one in the begining.
