Hey Slick, you're giving away all my cool tricks! Soon I will not be able to win any game any more!
2) I do not have verified it yet, but I think I have noticed after the Last patch that ships in queues on a planet without shipyards are automatically cleared when the turn is executed.
6) Never could make attack / load troops work reliably. I always use attack, move one sector away, load troops from previous sector. This works always. I do not know why the load order is often ignored otherwise.
10) Too much income, too little spaceyards? Retrofit series are your friend! Roughly doubles your shipyard capacity. Save cost and time by training while retrofitting.
15) Always build at least one resource converter more than needed. Nothing more crippling than a conquered resource converter if it is your only one. One class III converter can only convert a maximum of 1,365,000 resources into 955,500 of a different type per turn. If you try to convert more, the orders will be queued into the next turn.
