So basically, an online company has basically taken almost all of the A Game of Thrones boardgame mechanics, rethemed and repackaged them, and put them online. It's shady, lacks courtesy, but on the other hand it's currently the only good way to play this game online. It's called War of the Realm.
For those that don't know, the A Game of Thrones boardgame was a bit like the old Avalon Hill boardgame, Diplomacy, except a bit more complex and based in a fantasy universe. The idea is that players have to conquer the game, but don't really have enough strength to do it alone. As such, they must make alliances to achieve their goals, all the while backstabbing other players and watching out for knife in the back as well.
It does some things the boardgame doesn't, namely add new maps with different setups, but for the most part all the mechanics are the same. The new maps aren't as strategically interesting as the boardgame's map though. Part of the problem with the boardgame was finding the time and players to play the game.
Still, anyone want to start a game of this? There's a "casual" speed where you can log in to take your turn as it comes up, kind of like play by email, except you still log into the site to take your turn.
