Sorry to resurrect an old thread, but I thought it was warranted because it’s turning up in search engines.
While I do think more stats like this would be very useful in game (certainly more useful than the score), there are some mods I’ve found that at least try to tackle being able to see if you’ve got idle TCs. Both are modifications to the global queue graphics.
- Villager highlighter, makes it easier to see vills in the global queue: Mods Single - Age of Empires
- Alert for empty queue, makes the global queue RED when empty: Mods Single - Age of Empires
I’m not sure if these are still being actively developed though, if not it would be nice to spend some time working on them or even combining them into one. Of course the usefulness of this may depend on where you choose to have your global queue displayed and I don’t think the position can be changed based upon whether it’s empty or not.
