Ok so I went to war with the Drengin on "normal" lvl on the Demo. The war went really well bcuz they had maybe five ships all together (all heavy fighters beam weapons 3) I had six (4 fighters beam 2; 2 Medium size beam 4 shield 2).
Anyway I easily cut their forces down to size, and blockaded Drengia and Kona with the Medium ships, just marking time until I had researched Planetary invasion and bombardment.
Here's the problem:
They kept building heavy fighters and sending them up against me (one at a time) even though the combined stats of the two ships (in a fleet) were 10beam 4shield 2Armor 2Pd (I had a military starbase set up). These fighters could do NOTHING against me except allow my ships level up. I eventually had them both at lvl 30 and over 70hp.
My question is: Is this a bug, something the developers missed, the Demo, or is it just the dificulty setting I had it on? I would like to think that it was the latter but I don't know.
Also I've found that the AI doesn't consider production when assesing relative strength. I've had the drengin trying to bully me around when i had no standing army, but within 2 months I had the largest military in the galaxy and conquered the Drengin before the end of the Year (again on Normal) please tell me this is the difficulty setting.
