8/10/2011 Update: This is based on version 1 of the game. Much has changed in version 2, so don't take this as gospel unless someone updates it.

Key to the "Awesome" column:

♦     Not useful         U - Can be upgraded -- see below.
♦♦    Meh                ! - Only lasts one night! Waste of resources.
♦♦♦   Nice to have       
♦♦♦♦  Get it if you can  N - number of nuts and bolts required
♦♦♦♦♦ MUST HAVE ASAP     D - number of defensive objects required
N/A   Purely defensive upgrade - awesomeness depends on your choices
                                 and what you have in the bank.

Awesomeness:

  • Workshop upgrades only really help with the epic projects. The gains for the rest are negligible.
  • Watch tower upgrades up to level 3 are practically required for worry-free expeditions. The rest is nice to have.
  • Search tower upgrades are important to always have nearby undepleted areas.
  • Great pit upgrades are pretty meh. Upgrade the upgradeable wall instead, if you can.
  • Upgradeable pit upgrades are nice, but finite. Even 51 defense is nothing to sneeze at, but they only help you so much.
  • Defensive focus upgrades are pretty much a must-have. When everything is built and everything is upgraded, only defensive focus keeps improving your defense with every single defensive item. They outscore upgradeable wall after the 42nd defensive item circa.
  • Pump upgrades are nice to have but hardly earth-breaking.
  • Water turret upgrades seem to do more harm than good...

The French do not agree with my assessments and see getting a level 5 workshop as a requirement for a successful city.

For your consideration: all buildings, fully upgraded, give a total of 1783 defense (2118 defense including all the temporary projects.) According to PataPata, the average attack for day 17 is 1738. Defensive focus is that important :) –  badp Dec 17 '10 at 12:02

I agree that defensive focus is important eventually, but no town I've ever been in had anywhere near the number of defensive items your current town does. Even our town at day 14 got more defense from pit upgrades than building defensive focus. So I think your impression of it might be skewed by the success of your current town's scavenging. I think it is important later game, but not so much early. –  bwarner Dec 17 '10 at 12:28
    
@bwarner It's quite possible that what you mean is true -- we do have a ton of scavengers in our city (9?), while during beta heroes were few and far between. Still, everything else can only bring you so far. –  badp Dec 17 '10 at 12:32

ASCII win. However I recommend changing the "Awesomeness rating" to use a symbol which doesn't merge with itself - it's difficult to tell in a glance whether something has 4 or 5 awesomeness at the moment. –  Oak Dec 17 '10 at 12:40

@Badp I like that you had it as AP before, I would just change it to 2AP and 3AP. If someone wants to understand why those values are correct, they can ask a separate question. –  bwarner Feb 3 '11 at 18:42

This Die2Nite wiki has a list of everything that can be built, what it costs, and what it does.

And this other wiki has a list of the building tree along with the AP costs at each level of workshop upgrades. Which might be a useful tool to convince people not to do workshop upgrades...
