Actually you killed 60 ships in the south, and you're still in second place.
But not for long.
As far as the map, actually it's alomst exactly down the middle. My side looks bigger, but the systems are more spread out. In actuality I only have two more system then you do. Of course until we both see both sides it's difficult to say who has more planets available. I expect that will be close though.
It really does come down to the Talisman. You say you are afraid to try the warp points. And likely your fleets would have been banged up pretty bad if you tried them. But even if all your ships were destroyed my fleet woull have been too damaged to take advantage of the victory. On teh other hand your southern fleet obliterated 60 of my top ships and only got a few paint scratches to show for it. Actually my small sattelite group did more damage to your fleet when they came through then my 60 ships did 2 turns before. And even then I only damaged one ship. Now yoru fleet of 30 is free in my southern space.
My 51 ships in Dertran are hardly wandering. There is only one planet there I can get to. I can see that both warp points out of that system are well defended by your ships and sattelites. Or had you forgot about my stealth ships for a third time.
The only way I can win this is if my remaining stealth ships can do enough damage to you to collapse your ecoonmy before you can stop them. I seriously doubt that is possible. They have only managed to take out about 15 planets thus far. At best I may have managed to cause you to pause some of your build queues. And only temporarily I am sure.
