So it would seem, after many -many- hours, and hundreds of games (I put my QX9650 oc'd 4.0 to the test lemme tell ya... hehe...) trying dozens of strategies, etc, a thought occured to me. Why not try it on classic mode?
Apperently, under dynamic mode, the amount of seedlings on a given 'rescue-able' asteroid starts off with only a couple, vs the older, 'classic' mode, starts it off with max.
Bottom line, once I switched to classic, it took one pass of hide and seek, and one pass of badlands, and viola, got the achievement.
Now all I have left, is that pesky stalemate one, any suggestions?
