So, what is the best adventure/setting you've played/created?

My personal favorite was a tower. The group had just entered an empty town and just outside that town there was a big tower. Instead of the tower being built, it looked more like the tower had been carved out of stone. The group entered after passing by a blind homeless guy who said that inside the tower was what they sought. The tower looked like it was looped through countless dimensions and planes. After casting Detect Magic, one of the characters saw how every part of the tower was magical. On the way to the top they collected some books on the history of the tower and found out several things. At the top (after fighting off two vampires and beating a Minotaur in chess) they met the blind guy again who gave them what they most wanted. Two got powerful weapons, one got ring of air elemental control, one became a prophet and one got a powerful lovepotion to use on another member of the group.
And that's pretty much how it went.

I started something here on the Inn (got taken out by that bloody crash) that I rather enjoyed. I won't be giving up details as I may start it again. We shall see...But yes...it was my favorite, other than one my friend made, I enjoyed that, but cannot entirely remember it.

I think that my coolest experience with (A)DnD was the first real adventure I ever played. It was fantastic...

I had some experience in a dutch version of dnd, so the ways of playing were pretty known. It was the adventure that made it totally worth the buy.
We, the players, had to retrieve a powerful magical item called "the silver key", and that was also the title of the adventure.
We were hired by the government of a city that feared that orcs got a hold of said key. We were polymorphed into orcs and had to go investigate. The fun trick was that if a character started behaving like an orc, he would get a so called Orc point. You can only get as many orc points as your wisdom score before turning into an orc for real.
We had so much fun nominating eachother for orc points... .
It was great... perhaps one day I will bring that adventure to the inn

That's so awesome, Almerin! Makes me remember why I love playing tabletop RPGs!

(Haven't been able to find a group in a long time, though. Anyone from Jönköping, Sweden around here? )

My favourite setting has thus far been in the land of Drakenhorde. I do not want to say much more about it though. I am intending to make a game in the setting sometime, so watch for that!

I think the best is the thing im playing in right now under you Skari

I really like this town of yours, and just the general feel of the game..

If that couldn't be misunderstood, I don't know what could

I have two actually:

1) In one of my rare stints as a player I created an Elvin swordsman. The GM threw me for a loop when at first level the character was transported to an alternate dimension where Bromern Sal ruled. Yeah, that's right. Bromern Sal, at that time, was an accomplished arch-mage/assassin/fighter, and my character suddenly turned NPC tyrant ruler. The kicker? My lowly fighter became the leader of the rebellion against my epic character. It was amazing. The elf ended up dying while trying to save the lives of a number of his rebels who were to be publicly hung.

2) This one I GM'd. I've been running my friend's character through a campaign for twenty-one years now. Along the way we've added his wife, my wife, and now my eldest son to the group as well as many, many characters from players who've come and gone. Suffice it to say that these character's have a deep, rich history, and these players have a well-known style of playing them--particularly my wife who plays to spend time with me while otherwise referring to role-playing as playing house for grown-ups. She usually sits and doodles, paying only partial attention to the game.

Well, for this session I'd developed a scenario where a wealthy merchant approaches the group (well known for their heroics in the area) because his caravan had been raided, and his beautiful, young wife kidnapped. He was willing to give up his entire fortune for her safe return. So the group used magic to determine the location of this prize and ended up entering a tower of unknown origin that they quickly discovered was filled--museum like--with beautiful objects: sculptures, paintings, jewelry, etc.

I passed my wife a note as we usually do when discussing what time I'm going to end the session only this time it informed her that when the party holed up to recoup their spell usage and rest her character (an Elvin monk) was going to be the victim of a Magic Jar spell, and that if she'd like I could NPC her actions. To my surprise she opted to play it through.

When my friend's character (a Drizzt knock off) was on watch and the rest were slepping my wife described her character rising up and approaching his character. She then started speaking in character:

"How dare you. You think you can enter my home uninvited, pillage my belongings, and there would be no reprocussions? Did you think I'd let you live, little drow? How dare you!"

At which point she informed me that her monk was launching into attack on the drow. The player's response was priceless:

"Ack! She's possessed!" he screeched as he nearly toppled out of his chair while scooting frantically away from my wife.

The freed her from the wizard's control and eventually won the freedom of the merchant's wife (the merchant eventually became a political ally), but not before one character was turned to stone, two character's died, and another lost a limb (all fixed by magic).

I still chuckle when I picture his reaction. So surprised. So animated.
