Nisser ain't swedish, they are remnants of the old nordic religion and folkelore. In other words they are swedish, norwegian, icelandic and danish. Dunno if they have them in finnish folkelore as well, but could be.Darth IB said:I'm pretty sure we (sweden) invented the short elves (the ones who are santa's helpers nowadays). Except back in the day they were cruel bastards who would pretty much ruin your life if the porridge you gave it was too warm (and if you forgot to give it porridge, may God have mercy on your soul).
As for games, I'm not too sure though. Or actually, they could make Farmville almost interesting.
OP: In norway we also have nisser but we also have trolls (also old scandenavian folkelore)like nisser they are part of the mountainpeople but trolls are either humansize (where the only thing that can identify them are the tail) or their huge (these are horrible to look at, huge nose bended back large mouth and eat christians). The mountainpeople or mountainfolk tends to, acording to the myths steal people and turn them into mountainfolk.
Their origin is dverger/dwarfs(that's nisser) and jotuns (that's trolls)
