Revenge is fabulous!

Well Niko finally tracks down the man he thinks is responsible for being betrayed in the war, and it turned out that he's currently a flamboyant gay man dating a politician. So now what little plot the game had is gone and all that seems to be left is to go on assorted missions until the game stops giving them.

I was right though that the next act would use that last area and most likely the politician connection will come up eventually.
