has nothing to do with blame, i just dont think a game with soooo many possible paths and choices should end with one mission,
it a ROLE PLAYING GAME, so let the player continue the role. also as i stated earlier, they should make a patch as an "optional download"
to allow u to continue. if ur one of these crybabies who like the way the game ends...THEN DONT DOWNLOAD IT!
The game ends with 'one mission', as you put it, because that mission marks the end of the Courier's story. What that story is depends on the role you picked for the Courier, so if you don't want that role to end yet, don't finish the game.
By the way, allowing post-MQ play would actually
invalidate the role you're so attached to, because it would cease to have any meaning as you would never see the effects of all the decisions you made.
Sidenote: Am I the only one who sees the irony in being called a 'crybaby', because I like that the story ends, by someone who's wailing about that?
