I was playing SINS last weekend as Advent. It was a 6 free for all on a 3 star system map. The computer was getting really on my nerves. When i jump one of my fleets over to attack a planet, the enemy planet's defending fleet would jump to the planet i left open with just my defences. Then i would jump back or send another fleet to rescue the planet, then the comptuer jumped to another unoccupied planet. Then i got all the forces cornered in on planet but then i couldn't win cause there were 3 NPC with massives amounts of ships in one planet. In the end it was pratically a stalemate cause I couldn't attack without lossing all my forces and the NPCs couldn't get out.
