For those who want to change the quality names and want ideas for what to replace them with, here are some suggestions:

• Normal
• Fair
• Good
• Excellent
• Perfect

These are the best names and nobody can tell me otherwise ever:

-Normal-
+Fine+
*Superior*
≡Exceptional≡
☼Masterwork☼

Here's what I'll be using:
- Tier 1
- Tier 2
- Tier 3
- Tier 4
- Tier 5

These are the best names and nobody can tell me otherwise ever:

-Normal-
+Fine+
*Superior*

Sadly the Dwarf Fortress name format isn't possible with the current modding limitations :(

Sorry for the necro, but I added the DF names in with the symbols just now and they show up fine in game. Not sure if you fixed that or if that was a Wube change.

Oh yeah symbols are no problem. What I meant is that, in DF the quality is indicated by symbols around the item's name. Like "+copper pick+".
You can't do that in Factorio, even with my mod the format is strictly "Item name (Quality name)".

Ahhh, yeah, I'm not surprised that's not possible to implement.
