Budget Sword Barrel.
Guaranteed source of talking swords.
Sometimes trash is a measure of poor taste and not just poor killing capacity.

Funny you mention that. The talking sword I always remember from games would be Lilarcor from Baldur's Gate 2. That one was so infamous that there was a mod made for Morrowind to insert it, and to be fair it was a really funny adaptation. Funnily enough I don't remember one in Neverwinter Nights, though I don't think I ever completed Hordes of the Underdark all the way through (I did the main NWN campaign quite a few times, as well as Shadows of Undrentide).
I don't even see that many D&D-based games these days in general, though they might still be sticking to the isometric format since it is easier to make. I don't play a lot of isometric games these days. The last two were Grim Dawn and Tyranny. Very good games by all accounts, though not the sort that lend themselves very well to talking swords.
Can't say as I even looked into talking sword mods for Skyrim (I have been replaying it recently), though now I'm curious.
