So basically you're asking for a starbase that can phase jump. There are already mods which implement this. Personally I will always believe that "super units" will either by disappointingly easy to counter to unfairly powerful with no in between. If they can't be beaten by a swarm of weaker units, the game becomes a race to get to the super units. If they can be... well, that kind of defeats the whole point of a super unit, now doesn't it?
I don't think this is a good idea. Sins is and should stay about fleet rather than one enormous big ship imo.
Well duh, no one should rely on the super-vessel soley.
Sending it alone would be suicide but attacking it with a few units would also be. It would be the center of the fleet, not the fleet.
And if this super-vessel causes so much discrepency, then an option for mulitplayer...no starbases, no super vessels, no super weapons...or one option that does all 3 (etc. with other options in multiplayer).
And yes there is a middle ground.
Say, two players of equal skill level duke it out. One person goes for the supervessel while having a slightly smaller fleet and some starbases doing his defensive duties. Well the other person who goes for huge fleets can counter his super-vessel and smaller fleet with his huge fleet but it'd be close....only tactics would decide it....not 1000 missile frigates or 1 single super-vessel.
Also....there would have to be totally symmetric maps to allow for these to work....an equal chance to have the same amount of resources/planets/chokepoints. Many a time, when I'm playing single player (when I did play) I had a crappy starting set up and it made it impossible. It needs to be equal. Same amount and type of planets/bonuses/relics.
But then you have starbases clogging everything up as well...leading to as someone mentioned...a sandbox...
And, as everyone knows this game has a huge single player community (paradox!) and the average single-player player would love a huge ship to admire and use.
Not really a dream, considering I haven't played the game in about a year but more of a 'why not'?
And Darvin3, since you seem so opposed to this, idk if you play mp or sp but you can't deny that you wouldnt like to have the option to build such a vessel if you're playing against 1 easy ai or 9 hard ai's or just fooling around with a friend(no homo). Or better yet....destroy one of them and see it explode....
