The deliverance engine has multiple applications, rather than one established purpose.  It can: neutralize an enemy colony through culture(especially if the shots are staggered at one site), help establish allegiance boosts early at newly acquired colonies, boost combat damage by 25% for your ships at the site of impact, provide intel through the eyes of the converted(IIRC) skill that reveals areas influenced by your culture, improve shield mitigation for your ships since culture techs are prerequisites. 

You gain 'diplomacy points' through establishing relationships.  When those points get high enough, you automatically win and the game ends.  It can be kind of a let down at first. 

For the black market, enable the 'mini-window' from the options menus.  Then, hold Shift to purchase or sell quantities of 500 when the price looks good.  You can also set resources aside to sell to other players.  You have to wait until someone purchases, but you'll get a higher return.

Never bothered trying to set one factory one way and another differently.  If you try to individually select the factories instead of the planet and the ships continue to spew out in the order purchased, then I'm not sure you'll ever see that change.  Remember that I said 'if' though, as I haven't personally tried that method. 

1 starbase per gravity well is the limit, excepting stars themselves which can hold 4.  I had a map with 3 systems where my system was the apex of an isoceles triangle.  So I plopped 4 starbases down along the incoming fronts with mass disorientation and meteor control.  Hilarity ensued whenever someone tried to jump into the star system. 

Why when i put say 1000 metal on black market for sell at a low price  does the ai not buy ? I dont see any additinal credits income doing this way on the credits tab.

Just to clarify on this. Diplomatic victory allows you to win by accumulating enough diplomatic points (envoys, research etc.). Allied victors sets the number players that can jointly win a game. For example if the number of allied victors is set to two, only one team of two can win the game (though you still can form an alliance of four, its going to have to split at some point).

Ya, I wanted that too... But will anyone go for adding mass disorientation to the Deliverance Engine

Random thought:

Perhaps the Novalith could reduce enemy ship accuracy at the site of impact?

I judge the super weapons by how I've seen them used in online play. Kostura's where brutal and could be deployed with very little effort (i.e. no pre-reqs on research other than 8 labs). I've never seen someone invest in a Deliverance engine and make a difference in the game. It MIGHT make sense to build a deliverance engine in a team game if you are pure eco and can invest eight civ labs into this one tech as there very little after 3 labs worth investing in. Chances are you fed away this money though so they could get 25% or more ships which last beyond 150 seconds.

Comparison of Hostility techs versus deliverance engine (excludes cost for labs and logistic space)

30% Laser/Beam damage upgrades: 11,000/1525/2550

30% Laser/Beam Plasma damage: 16,500/2300/3825 (excludes rate of fire increase on plasma which is 7 lab).

One deliverance Engine: 16700/1975/2725

Two deliverance Engines: 24700/2575/3225

Other options:

Build a Halcyon and Rapture and buff your fleet by up to 22% rof and decrease their damage by almost 50%.

Build culture centers on your border worlds so you are fighting more often in your own culture for the shield mitigation benefit...

IMO if your building your own fleet it's hard to justify deliverance engines until after you've maxed out the permanent upgrades especially as it requires at-least 2 engines to keep the damage buff semi-permanent (3 to keep it overlapping and permanent)

Yes, if you can afford it and don't have much room to move up in fleet supply it can make a decent fleet enhancement.

I'd still like to see something added to the deliverance engine though. One less aggressive thought is to have it disable enemy culture centers in the targetted gravity well for the duration of the effect.

I liked the idea of Mass Disorientation being added to the Deliverance Engine  

Only if Kostura went back to pre-nerf tho lol and the Novalith would need a slight buff in response as well.

Thx Annatar, for the tip on using the Deliverence Engine, I've never seen that before!

The Novalith's trade debuff lasts 30 minutes.  I was testing it - its not permanent.  And its not "100%".  Its actually 50% of prior income, so it doesn't actually interrupt a trade route either!  3500 planet health damage per shot.  Meaning 2 shots to kill a homeworld.  Most planets die to one shot.  Multiple Novaliths can be a game winner, if you methodically kill all. 

Destroyed planets say: "Can not colonize due to strong bombardment raditation", but that only lasts a couple minutes!  And:  "Max Population -40%" which lasts as long as "Trade Income -100%" (in red).  But I don't actually see a population growth effect? 

Anyone ever been able to figure out how Kostura structure damage is calcuated?  It doesn't appear to be either a straight damage amount or percentage.  Maybe a combination, that varies per type of structure?  I think people forget that a Kostura shot opens a temporary phase lane to the targeted planet.

Are you sure its 12.5%?   25% make more sense!   Thats whats I had it calculated as here.

Thx, Maybe armor is it.  So the base Kostura damage rate must be 1250?  Anyone?

Why is when i run sins in a window it lags but in fullscreen  it doesnt ?

Whats the most efficent way to manage fleets when you have >20 planets owned i mean it gets to a point where you dont have enough to defend and attack at the same time so you get stuck in a loop of moving fleets about to each planet that gets attacked trying to defend?

Where can i find replays for sins empire diplomacy latest version ?

For the first its probably whatever stuff you have in the background, and windowed mode is a bit more intensive task.

Starbases were designed for exactly that problem, when you have more enemies attacking you then you can have fleets to meet them.

Yes, for trade ports the answer is almost always yes, for refineries it depends.  A long trade line is one of the best investments in the game - biggest and quickest payback, so maximize it as much as possible.  The payback for refineries generally only makes sense on select planets with lots of phase lanes out and more importantly lots of metal & crystal 'rocks' adjoining.  Some say: the breakeven point is 10-12 'rocks'.  If 15 or more, build up to 3 refineries, as long as that doesn't break your trade route.

Why is it sometimes when i have multiple trade ports in a line of planets the white line doesnt link them all up is this a bug ?
