I had an idea: Currently you can only jump from one star to another the the suns gravwell.
Especially with a whole system in a players hand this is an incredibly awkward chokepoint for others to invade (not to meantion that with the culture its very hard to get a foothold.
If we had multiple nodes to enter a system we had more chances to raid the enemy or enter the system.
My suggestion is that gas giants which are neutral territory aswell could be entry points for incoming fleets aswell.
Of course early ggame when everyone is still struggling only the sun should be the jumppoint, but later on they should open up aswell
(possibility for a new, higher tier research after long range jumps)Idea would either be that they would be a one way street: jumping from a sun to a gas giant (sun has to be the entry point)
or a two way system, gas giant to distant sun also possible.
Or that you could even travel between gas giants from different systems.
Since it is not possible to travel between gas giants of the same system can be explained that the graviational forces of the nearby planets don´t allow the long distance jump.
So you could untilize the gas giants only between systems

I think the game with multiple systems would get much more dynamic and fun as you could try to invade and harass at multiple fronts

What do you think?
