And that folks would be the end of Batman Arkham Asylum... well at least of the first playthrough, normal beat, all collectables collected... now to go back some day and beat all the challenges and the game on hard =P.
I am now in the same boat. One feverish weekend of major vigilantism and I am now Batmanned out. I did love it, but it would take a miracle for me to ever get 1000/1000.
