When I started out, I went on dominating the current area when I found the rotating asteroid. I tried getting one onto it to see what happens, but I missed it, so I was thinking "oh well, maybe it'll return"
It did. With 90 enemy seedlings.

(I quit the match)
The second try I had 20 scouts on Transport A. I was monitoring the asteroid for quite a bit and found Transport B. 20 went from A to B. Found the enemy hive, went to the safety place, saw in horror that it just sent 100++ seedlings to transport B, found out I had only 30 seedlings at the starting area.

(quitted)
The third try I captured the upper 2 asteroids first (Just to save up on seedlings) and sent all (50-ish) to Transport A. Didn't hop from A to B. Found spikeland (sent a scout to the safe area). Found the land where they had some unoccupied space. Dyson'd the two just in time when my starting area got overrun. Had a happy family of 80-ish. Fended off waves of low-energy-but-high-attack-and-speed seedlings in 150's. Got to their main production house (with 8 trees), captured it. Received 500 enemy seedlings from transport B.

(also quitted)
Fourth try was the same as third, just that I managed to get better astroids (so much so that I made 2 defence trees on the first neighbouring asteroid to try to buy time). Didn't work. See try 3.

(quiiiiit)
After reading this thread, I thought maybe I should take things slowly. Made more dyson trees on the starting usual 3. Only managed 25 on A this time. Went on to attack spikeland. Broke the lone defence tree, but didn't have enough to sap. Quickly gathered the 100++ I had waiting for B. Got all of them to B while they started the attack. They capped the first 2 when I just arrived. Was racing against time to sap spikeland 1 when they capped my starting point. (too late to quit. crashed)
