But wouldn';t Pakistan be better off not hiding OBL? It would save them the eventual embarrassment yet the country could still collect US taxpayer money. I believe that he may have died in 2001 and that his body was frozen so that he could be "killed" for political points. How convenient it was to bury the body at sea. Now we will never know.
Bioware can make epilogues though. Just look at Dragon Age. Not only does the final fight finish differently depending on (some) choices, but once the game ends you have pages and pages of text telling you what happens in the world once everything is over. It isn’;t much, just some simple lines, but it helps give some sense of closure to the events of the game.
