I basically meant this to be the perfect playthrough on the hardest difficulty. This is on Extreme, but as long as you don't pause (which I don't) and never reload (which I also don't, except to save, quit and reload to deal with a bug), then Extreme is actually more difficult than Survival.

I finish the playthrough with all upgrades by day 28, which is quite a bit faster than any of the other Extreme/Survival playthroughs I've seen on Youtube.

The key points are unlocking the Labor laws on day 6 and the Engineer laws on day 10. Unlocking the Labor Laws allows you to use Two Shifts, which is a massive increase in productivity, especially for your technology progression. The other key is getting your motivation high and keeping it high, which is mostly done by using Pleasure House and Hearty Meals.

Just for the fun of it I also did No Censorship and No Stealing, so no tricking the guys at the storehouse or taking the forgotten supplies. They're really not needed anyway.
