Solved - Gamers in a fantasy world [s]

[David]

Gamers join around a table. They are sent to the fantasy world they are gaming.

Details:
The person who was playing the one-handed thief ran into trouble with a nobleman
Healing potions play a major role
The group eventually makes revolvers
They manage one trip back to the real world, but had to return

There have been numerous books with this premise, but this sounds like The Sleeping Dragon as I remember them making a trip back to 'our' world - I think to confront the college professor who sent them there in the first place.

Seconded! My first thought was The Sleeping Dragon too.

[Kris]

I popped in to suggest the Guardians of the Flame series as well.

That is it!

Thanks much, all
