Re: Epic Project Tasks... (1 Token Per Week?)
You need to focus on upgrading your storage (350 is the max), or save up a lot of simoleons to spend at the global trade HQ. I recommend a minimum 100,000 if you're aiming for gold.
Note that different specialisation buildings yield different epic points.
I went ahead and replaced most of mine with 3 point buildings, e.g. all universities for education (except for gambling, there aren't any 3 point building!).
The required parts for each building is random, 1 point buildings do not require easier/cheaper parts, or less parts (but they seem to get harder as you approach 160).
My specialisations have around 6 x 3 point buildings each, and I try and focus on completing only those buildings for 3 points, sometimes I do a 2 point building if it's cheap parts.
I now have 6 x gold epic projects, and 2 x silver. I'm level 53, I started with 280 storage when the update came out, but i've increased to 350 now.
What I do is try and stock 3-5 of each item before I start an epic project building (except for parts that are easily obtained from global trade HQ).
