I just finished Technocrat's excellent Technobabylon series up to the third installment. I enjoyed it a lot. I also got stuck on the third installment a lot, and wished I had a walkthrough when sifting through everyone's various hints.
In response to Three Headed Monkey's observation
that Technobabylon III is significantly tougher than it's predecessors (And having a rediculous amount of trouble with it myself), I decided to spend a couple hours putting together a walkthrough.
It tries to be bare bones about the steps to be taken to solve the game, so it tries to avoid spoilers and doesn't spend too much time giving hints; just straight up solutions here.
I know it's about a year too late, but hope it helps someone!
[NINJA EDIT: I just noticed AGA's sticky regarding walkthrough's and realized the mods probably don't want whole walkthroughs posted directly in the Hints and Tips board. So, here's a link to a .txt version of the walkthrough.
