As I vote, I must say: I'm conflicted. Been playing the game a little over a week, during the summer. Here's my thoughts..... At Night, I want an ~8 hr Build que, and during the day I want a ~2 hr Build que. At Night, I actually like the Speed 1 world, like the one I am playing in, Lambda. However, during the day, I would prefer a World Speed of 4. This is a weighted average of 8 hour periods.... (4*2+1*1)/3 = 3. Also, the effect maybe, I wouldn't have to Upgrade my Senate so much for the Speed, and Upgrade my Warehouse more so for the idle Build times... which I could then use for other stuff!
