Inspired by this (closed) thread by Magic Rub, it occured to me that Trolls are very different from one fantasy source to the next.
Has anyone ever used a different kind of troll in their D&D game? What did the players do? How did they react to the lack of regeneration etc.
I hope my subject line doesn't invite flames: D&D trolls would die, and pratchett trolls would become really, really stupid. 
edit: Oh, one more thing: Do not even mention those blasted dolls with big hair. Those are not Trolls. I am quite sure that that was just a misspelling for dolls.

Thanks for the re-start Rav.

The old thread may have been silly in part, but the intent was all the same. Trolls (& to some extent most goblinoid races, heck all creatures, but we're not talking about all creatures) Have been changed & re-changed, sometimes drastically, from one fantasy setting to the next.
My favorite are the trolls from the "Gnome" Books, due mostly to childhood nostalgia, & all those pretty pictures (which are nice when you're young & can't read yet)

.
They were evil, greedy, dirty, sub human... & yet still in some way relatable to us

.
I'm with Rav, I hate the Troll Dolls!
(I'll spare the picture on this one)
They're useless, market tools! I used them simply to flavour my point.
The idea of PC Trolls has always sparked my imagination in D&D, which is why I made note of the Everquest Trolls.
I would have noted The War hammer trolls, but didn't know they existed. (& They sound different yet again)
Warhammer trolls (there are probably a million more kinds?????)
Here's two that I could find examples of first the "Marsh Troll" & second the "Chaos Troll"
Here's what Warhammer claims to be a "Basic Troll"
Sure it is!
As Dr. Midnight noted, "What, no love for the trolls from Willow???"
They look like nuked wookies, what more can I say.
Anyone remember Troll the movie?
Looks like a nice guy, & a bit like the willow troll
Then there's the "Norwegian trolls"
I've seen these when I was little, a guy who had a cabin near my Grandma's Collected these things. He hid them all around his cabin.
The list goes on & on. If you have more examples, written, stats, or pics, pop them up.
