Bigg, there is a big quantity of weidu mods nowadays which in turn implement almost solely new npcs. Quality? well, some are good some are crap.
What are TDD's qualities:
1. TDD was the first quest mod.
2. TDD had some technical advancements used first in that mod.
3. TDD implemented kits too.
All this was done with much less knowledge than nowadays.
Sure, it sucks now. Sure it had bugs all around. Sure it crashed.
But, which mod doesn't?
And nowadays, there are much better tools.
If TDD didn't exist, i would surely not have joined the modding scene
And i wouldn't have started my own modding tool either, it started as a TDD bug finder tool.
So, give credit where credit is due.
