The games tooltips are poorly designed and uninformative. The Industry Standard and consumer expectation for tooltip are Nested Tooltips with rich text and explanations.
These can be seen in such games as
- Victoria 3
- At The Gates
- Old World
Releasing a modern strategy game without nested tooltips in this day and age is tantamount to a failure to follow best practices and delivering a non-viable product from a UX point of view.
