Save/reload...
much, much less than before, since reload just takes way too long, and only over large stretches to see if a different strategy will give a different result (Oracle rush vs Pyramid rush vs Currency/Optics/Liberalism/Riflemen beeline). I will only finish one map at a time to victory or defeat, though, since I don't want to have the victory screen filled with 15 victories and 30 defeats from a single map. The game is more fun once I have gotten over the tendency to reload for every bad roll.
I am playing Emperor now so it would probably be more like 30 games quit for each victory until I get a handle on the pace of the AI. I have no finished games on this level yet, though, but I'm on my third attempt.
