The charr dueling mini game was called bar brawl and would obviously be held in an instanced version of that bar in the Black Citadel you visited in your personal story. I forgot its name, it’s been too long since I last played.
ANet didn’t have time to implement all the games. Those games have been already planned and worked into the design of the cities, such as the shooting gallery and polymock arenas. The moa race track and miniature duel rink can be visited in game right now. They just don’t take you to an instance with the actual game, like keg brawl does.
I would like to see them being able to make games take place in the main map sometime in the future. I don’t know if that’ll be feasible or possible, though.
That first part is actually incorrect; the location of bar brawl is known. Several NPC’s around the city will tell you that it takes place in Divinity’s Reach at the Busted Flagon POI west of Dwayna Road. You can find out more about activities in my signature, I’ve found 9 so far.
I agree with a lot of what was said in this thread. It’s the worst type of irony, bordering on hypocrisy, that the pre-launch hype created by Anet’s infamous “When-it’s-ready” strategy has left those waiting for these mini games severely disappointed.
gamereactor.eu: Alright. Because I was thinking about, you brought up the bar brawl, for example Funcom had something like that planned for Age of Conan, and I’m not sure that made it in at launch. Is there any risk that something similar would happen to the activities? Or is it an integral part of the game experience in itself?
Anet Dev #1: These are getting built into the game itself, they will be there at launch. They are not something that we will tack on later, they are part of the cities.
Anet Dev #2: One of the things I can say is that we tend to, you know, we were pretty tight-lipped about the game for a long time and we tend not to talk about things unless they are actually in the game. So when we talk about activities, like when we talk about the bar brawl, or the shooting gallery, because they are actually in the game you can go in and experience them right now. And so there is actually very little chance that most things we talk about are not going to make it into the game just because we run out of time or anything like that. Because, as I said, we tend not to talk about things unless we’re very, very certain that we can do them. Certain as in they are in already.

Coming from a Kegmaster and leader of a Keg Brawl guild, this is the source of my sorrows and my anger for the past seven months. Please Anet, for the love of Grenth, get activities in the game x.x
