Picture your typical generic rts , your factories produce 1 unit, then it trickles out and you use it , because the enemy has 1 unit built too. So you meet in middle and its 1v1 , then ur second unit comes and its 2v2 ,then 3v3 then 4v4 ..then back to 3v3 as your 1st unit dies..erm boring.
I think fleet building is better , you will get 30 out then its 30 v 30. I think if yo build in fleets in will be cheaper , since your shipyard engineers have already got their tools out , and they can mass order parts and stuff to build the ships together...ok some excuse to make fleet building worthwhile basically.
Just wondering what Sins has install for us with building ships.
