I have just started getting back into sins after having many months away from it (6 months), i used to be to handle the hard AI's ok, i have started at trying to take on the harder levels, i have always been slow at expansion and have allowed myself to get bottled in so to speak. I play as TEC and like to build tons of trade ports and expand slowly. I have made myself expand quicker now, but never fill comfortable with the lack of credits i have compared to my slow starts and the lack of funds to invest in fleet, research, but i do have many more planets.
Ayway to the point, having reviewed a few games it comes clear to me that the harder level AI's have higher crystal and metal incomes overal and from astroids. This has got me wondering should i drop a trade port per planet for a refinery or drop a trade port for refinerys when you have many nearby planets.
Please could you comment, state what you think about using refinery's, how many to use, when not to use and balancing refinerys with trade ports.
P.S if this is already been discussed in the forums i apologise for doubling up.
