Amnoon Oasis Boardgame
With the release of the new heart of the mists map they've added a VIP section to it that can only be accessed by a tiny amount of people (21 to 29 players per region, per month). In it you can find a small board game, tucked away in a corner on a table.
This board game uses a combination of playing cards and different kind of dice and has room for up to four players. The cards and glyphs all have a distinct Elonian feel to it and one of the meshes is called AmnoonOasisLattice1:Dice1.
With the amount of textures available it is possible we'll be getting a new mini game in the future. Now I do not understand why they chose to put an item that in my opinion could've sparked quite some hype in a location that only 0.0000001% of the population will ever be able to visit and definitely would've ignored.
Anyhow, enough of my complaints, enjoy!
