The only game where producing 20,000 of something per minute is considered "barely enough".

It is also one of games when you plan to sit for a half-hour session "to fix a small bottleneck".

Then suddenly it's 4 in the morning and that bottleneck is nowhere near being fixed because you tried fixing the other bottleneck first, and there was a power outage, and aliens spat on your walls, and a mine got depleted, and better ammo tech got done, so you needed to set it up so aliens wouldn't spit to so much on your walls, and a train got stuck so you had to rework a junction and... wait, how is 6 AM now?
