Tell me your fav unique unit, and why your unit choice is the best. And if there were a UU that you would like to be able to give to a different civ, mention that too. Personally, I believe that the Fast Worker is the penultimate of UUs for a million reasons, so I shall just name the highlights.
- No need to upgrade
- No need to wait for scientific advancements
- Saves multiple turns by moving into hills, forest, jungle, etc.
- if you select no barbarians, he is more effective as a scout than a scout
- when building roads to resources like fur (in ice), he can move and build in the same turn
- his time saving movement can mean the difference between building a wonder or losing it (chop trees)
