So, base is clearly inferior to the previous silver boxes. The main benefits of the base are control over what you craft, ability to craft epics/power kits/legendaries and gold income, but it comes with increased prices and lengthy build times, not to mention the cost and time spent upgrading your base to get these benefits. I feel that most items are overpriced and take too long to make, and would like to see either a moderate decrease in build time or minor decrease in costs of cards. This would encourage people to convert to base. At least add in a few achievements for crafting cards and upgrading buildings. It is much less efficient to build cards in the base if you are trying to upgrade items compared to just buying a ton of silver boxes, and the chances for epics/power kits are already included in the silver boxes.
This one is absolutely fantastic to drive, all rounded, all resistances in order, no module slot left empty, 1000kgs, all OCD checklist boxes ticked. Uses swoop.
